data returned from useOne is always undefined even if the query is responding correctly

I have this graphql based useOne implementation. The request and response is okay when checked in the network tab but the data returned by the useOne() hook is undefined.

const { data, error } = useOne({
    resource: 'users',
    id: '2808d117-590e-4659-8520-40273115040b',
    meta: {
      gqlQuery: USERS_QUERY,
    },
  });

  console.log(data, error);

const { data, error } = useOne({
    resource: 'users',
    id: '2808d117-590e-4659-8520-40273115040b',
    meta: {
      gqlQuery: USERS_QUERY,
    },
  });

  console.log(data, error);

Hi @KeyBored. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- It seems like you are using the useOne hook correctly, but there might be a few things to check to ensure that the data is returned properly. 1. Check the dataProvider Configuration: Ensure that your dataProvider is correctly set up to handle GraphQL queries. The useOne hook relies on the getOne method from the dataProvider. 2. Verify the Query Key: The useOne hook uses a query key to cache the data. Ensure that the query key is correctly generated from the provided properties. You can use the TanStack Query devtools to inspect the query key. 3. Check the meta Property: Ensure that the meta property is correctly passed and that USERS_QUERY is correctly defined and used in your dataProvider. 4. Inspect the error Object: The error object might provide more insights into why the data is not being returned. Ensure to log and inspect it. Here is a refined version of your code with additional logging for debugging:

const { data, error, isLoading } = useOne({
    resource: 'users',
    id: '2808d117-590e-4659-8520-40273115040b',
    meta: {
      gqlQuery: USERS_QUERY,
    },
  });

console.log('Data:', data);
console.log('Error:', error);
console.log('Is Loading:', isLoading);

const { data, error, isLoading } = useOne({
    resource: 'users',
    id: '2808d117-590e-4659-8520-40273115040b',
    meta: {
      gqlQuery: USERS_QUERY,
    },
  });

console.log('Data:', data);
console.log('Error:', error);
console.log('Is Loading:', isLoading);

If the issue persists, you might want to check the following: - Ensure dataProvider is correctly handling the gqlQuery: The dataProvider should be able to interpret and execute the GraphQL query provided in the meta property. - Check the useOne Hook Implementation: Ensure that the useOne hook is correctly implemented and that there are no issues with the hook itself. Refer to the useOne documentation (https://refine.dev/docs/data/hooks/use-one/) for more details. If none of these steps resolve the issue, you might want to refer to the GitHub issue (https://github.com/refinedev/refine/issues/5312) related to the useOne hook's return type being incorrect. This might provide additional context or solutions. For more detailed information, you can refer to the following documentation: - useOne Documentation (https://refine.dev/docs/data/hooks/use-one/) - Data Provider Documentation (https://refine.dev/docs/data/data-provider/) If you need further assistance, please provide more details about your dataProvider configuration and the USERS_QUERY definition. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Is this dataProvider config correct?

const client = new GraphQLClient(API_URL, {
  headers: {
    'x-hasura-admin-secret': HASURA_ADMIN_SECRET,
  },
});
const hasuraDataProvider = dataProvider(client);

<Refine
 ...
 dataProvider={hasuraDataProvider}
 ...
/>

const client = new GraphQLClient(API_URL, {
  headers: {
    'x-hasura-admin-secret': HASURA_ADMIN_SECRET,
  },
});
const hasuraDataProvider = dataProvider(client);

<Refine
 ...
 dataProvider={hasuraDataProvider}
 ...
/>

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the information provided in the knowledge sources, your dataProvider configuration for a GraphQL client seems to be on the right track. However, there are a few things to ensure: 1. Ensure dataProvider is correctly imported and configured: Make sure that the dataProvider function you are using is correctly imported and configured to work with GraphQL. 2. Check the GraphQLClient Configuration: Ensure that the GraphQLClient is correctly set up to handle the headers and the API URL. Here is a refined version of your dataProvider configuration:

import { GraphQLClient } from 'graphql-request';
import { dataProvider } from '@refinedev/hasura'; // Ensure this is the correct import for your GraphQL data provider

const client = new GraphQLClient(API_URL, {
  headers: {
    'x-hasura-admin-secret': HASURA_ADMIN_SECRET,
  },
});

const hasuraDataProvider = dataProvider(client);

<Refine
  ...
  dataProvider={hasuraDataProvider}
  ...
/>

import { GraphQLClient } from 'graphql-request';
import { dataProvider } from '@refinedev/hasura'; // Ensure this is the correct import for your GraphQL data provider

const client = new GraphQLClient(API_URL, {
  headers: {
    'x-hasura-admin-secret': HASURA_ADMIN_SECRET,
  },
});

const hasuraDataProvider = dataProvider(client);

<Refine
  ...
  dataProvider={hasuraDataProvider}
  ...
/>

Additional Steps to Verify: 1. Ensure Correct Import: Verify that the dataProvider you are importing is the correct one for your GraphQL setup. For example, if you are using Hasura, ensure you are importing from the correct package. 2. Check the API URL and Headers: Ensure that API_URL and HASURA_ADMIN_SECRET are correctly defined and accessible in your environment. 3. Test the Configuration: After setting up, test the configuration by making a simple query to ensure that the dataProvider is working as expected. For more detailed information, you can refer to the Data Provider Documentation (https://refine.dev/docs/data/data-provider/) and the specific documentation for the GraphQL data provider you are using. If you encounter any issues, please provide more details about the specific dataProvider package you are using and any error messages you receive. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai yes, it's correct. what else can go wrong then?

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If your dataProvider configuration is correct and you are still facing issues with useOne returning undefined, here are a few additional things to check: 1. Check the GraphQL Query Ensure that the USERS_QUERY is correctly defined and matches the expected structure. The query should be correctly fetching the data you need. 2. Verify the Response Structure Ensure that the response structure from your GraphQL query matches what useOne expects. The dataProvider might be looking for a specific structure in the response. 3. Inspect the Network Response Since you mentioned that the network tab shows the correct response, inspect the exact structure of the response. Ensure that the data is nested correctly and accessible. 4. Check the meta Property Ensure that the meta property is correctly passed and that USERS_QUERY is correctly defined and used in your dataProvider. 5. Use DevTools for Debugging Use the TanStack Query Devtools to inspect the query key and the cached data. This can help you understand if the data is being cached correctly. 6. Error Handling Inspect the error object returned by useOne to see if there are any clues about what might be going wrong. Example Code with Additional Logging Here is an example with additional logging to help debug the issue:

const { data, error, isLoading } = useOne({
    resource: 'users',
    id: '2808d117-590e-4659-8520-40273115040b',
    meta: {
      gqlQuery: USERS_QUERY,
    },
  });

console.log('Data:', data);
console.log('Error:', error);
console.log('Is Loading:', isLoading);

const { data, error, isLoading } = useOne({
    resource: 'users',
    id: '2808d117-590e-4659-8520-40273115040b',
    meta: {
      gqlQuery: USERS_QUERY,
    },
  });

console.log('Data:', data);
console.log('Error:', error);
console.log('Is Loading:', isLoading);

Documentation and Resources Refer to the following documentation for more details: - useOne Documentation (https://refine.dev/docs/data/hooks/use-one/) - Data Provider Documentation (https://refine.dev/docs/data/data-provider/) Final Steps If none of these steps resolve the issue, consider creating a minimal reproducible example and sharing it on the Refine GitHub Issues (https://github.com/refinedev/refine/issues) page for further assistance. This will help the community and maintainers to provide more targeted help. If you need further assistance, please provide more details about your dataProvider configuration and the USERS_QUERY definition. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Can I use useCustom() for a graphql query?

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can use the useCustom hook for a GraphQL query in refine. The useCustom hook is designed to send custom query requests using the TanStack Query advantages and can be configured to work with GraphQL queries. Basic Usage Here is an example of how you can use the useCustom hook for a GraphQL query:

import { useCustom, useApiUrl } from "@refinedev/core";

const apiUrl = useApiUrl();

const { data, isLoading, error } = useCustom({
  url: `${apiUrl}/graphql-endpoint`, // Replace with your GraphQL endpoint
  method: "post", // GraphQL queries are typically sent as POST requests
  config: {
    headers: {
      "Content-Type": "application/json",
      "x-custom-header": "foo-bar", // Add any custom headers if needed
    },
    body: JSON.stringify({
      query: `
        query {
          users {
            id
            name
            email
          }
        }
      `,
    }),
  },
});

console.log('Data:', data);
console.log('Error:', error);
console.log('Is Loading:', isLoading);

import { useCustom, useApiUrl } from "@refinedev/core";

const apiUrl = useApiUrl();

const { data, isLoading, error } = useCustom({
  url: `${apiUrl}/graphql-endpoint`, // Replace with your GraphQL endpoint
  method: "post", // GraphQL queries are typically sent as POST requests
  config: {
    headers: {
      "Content-Type": "application/json",
      "x-custom-header": "foo-bar", // Add any custom headers if needed
    },
    body: JSON.stringify({
      query: `
        query {
          users {
            id
            name
            email
          }
        }
      `,
    }),
  },
});

console.log('Data:', data);
console.log('Error:', error);
console.log('Is Loading:', isLoading);

Explanation - url: The URL of your GraphQL endpoint. - method: Typically, GraphQL queries are sent as POST requests. - config: Configuration object where you can set headers and the body of the request. The body should contain your GraphQL query. Additional Configuration You can also pass additional options using the queryOptions property if needed:

useCustom({
  url: `${apiUrl}/graphql-endpoint`,
  method: "post",
  config: {
    headers: {
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      query: `
        query {
          users {
            id
            name
            email
          }
        }
      `,
    }),
  },
  queryOptions: {
    retry: 3,
    enabled: true,
  },
});

useCustom({
  url: `${apiUrl}/graphql-endpoint`,
  method: "post",
  config: {
    headers: {
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      query: `
        query {
          users {
            id
            name
            email
          }
        }
      `,
    }),
  },
  queryOptions: {
    retry: 3,
    enabled: true,
  },
});

Documentation Links For more detailed information, you can refer to the following documentation: - useCustom Documentation (https://refine.dev/docs/data/hooks/use-custom/) - Data Provider Documentation (https://refine.dev/docs/data/data-provider/) By following these steps, you should be able to use the useCustom hook for your GraphQL queries effectively.

Let me check the knowledge base for you. One moment! :books: ---------------------- To resolve the error GraphQL operation name required, you need to ensure that your GraphQL query includes an operation name. In your case, the operation name is already included (getUsers), so the issue might be related to how the payload is being sent. Here is a refined version of your code with the correct payload structure:

const { data: customData, error, isLoading } = useCustom({
    method: 'post',
    url: API_URL,
    config: {
        headers: {
            'Content-Type': 'application/json',
        },
        body: JSON.stringify({
            query: `
                query getUsers {
                    users {
                        id
                        name
                        email
                    }
                }
            `,
        }),
    },
});

console.log('Data:', customData);
console.log('Error:', error);
console.log('Is Loading:', isLoading);

const { data: customData, error, isLoading } = useCustom({
    method: 'post',
    url: API_URL,
    config: {
        headers: {
            'Content-Type': 'application/json',
        },
        body: JSON.stringify({
            query: `
                query getUsers {
                    users {
                        id
                        name
                        email
                    }
                }
            `,
        }),
    },
});

console.log('Data:', customData);
console.log('Error:', error);
console.log('Is Loading:', isLoading);

Explanation - method: Set to 'post' as GraphQL queries are typically sent as POST requests. - url: The URL of your GraphQL endpoint. - config: Configuration object where you set headers and the body of the request. - headers: Ensure the Content-Type is set to application/json. - body: The body should contain your GraphQL query stringified as JSON. Additional Debugging - Inspect the error Object: If the error persists, inspect the error object returned by useCustom to get more details about what might be going wrong. - Check the Network Tab: Verify the request and response in the network tab of your browser's developer tools to ensure the request is being sent correctly. Documentation Links For more detailed information, you can refer to the following documentation: - useCustom Documentation (https://refine.dev/docs/data/hooks/use-custom/) - Data Provider Documentation (https://refine.dev/docs/data/data-provider/) By following these steps, you should be able to resolve the error and successfully fetch data using the useCustom hook with a GraphQL query. If you encounter any further issues, please provide more details for additional assistance. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
