Hi @chachi. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hmm, I don't know enough to give you a confident answer yet. The information extracts provided do not contain specific details about the issue you're experiencing with the graphqlDataProvider in refine. However, it's important to ensure that your changes are saved correctly and that your application is recompiled successfully after making changes. If you're using a hot-reloading development server, it should automatically pick up the changes. If not, you might need to manually restart your development server. If you're still having trouble, you might find it helpful to refer to the refine documentation (https://refine.dev/docs), particularly the sections related to data providers and GraphQL. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Ok so how do I overwrite the custom function from this provider?

import graphqlDataProvider, {
  GraphQLClient,
  liveProvider as graphqlLiveProvider,
} from '@refinedev/nestjs-query';
import { fetchWrapper } from './fetch-wrapper';
export const AUTH_API_BASE_URL = 'http://localhost:3000/auth/user';
export const API_URL = 'http://localhost:3000/graphql';
export const WS_URL = 'ws://localhost:3000/graphql';

export const client = new GraphQLClient(API_URL, {
  fetch: (url: string, options: RequestInit) => {
    try {
      return fetchWrapper(url, options);
    } catch (error) {
      return Promise.reject(error as Error);
    }
  },
});

export const dataProvider = graphqlDataProvider(client);

import graphqlDataProvider, {
  GraphQLClient,
  liveProvider as graphqlLiveProvider,
} from '@refinedev/nestjs-query';
import { fetchWrapper } from './fetch-wrapper';
export const AUTH_API_BASE_URL = 'http://localhost:3000/auth/user';
export const API_URL = 'http://localhost:3000/graphql';
export const WS_URL = 'ws://localhost:3000/graphql';

export const client = new GraphQLClient(API_URL, {
  fetch: (url: string, options: RequestInit) => {
    try {
      return fetchWrapper(url, options);
    } catch (error) {
      return Promise.reject(error as Error);
    }
  },
});

export const dataProvider = graphqlDataProvider(client);

Let me check the knowledge base for you. One moment! :books: ---------------------- To override a specific function of your data provider, you can use the spread syntax (...) to spread the existing data provider and then provide your own implementation of the function you want to override. Here's an example of how you can override the update function:

const myDataProvider = {  
 ...dataProvider,  
 update: async ({ resource, id, variables, meta }) => {  
 console.log("Overriding the update function");  
  
 // You can either send a request from scratch or use the original function  
 return await dataProvider.update({ resource, id, variables, meta });  
 },  
};

const myDataProvider = {  
 ...dataProvider,  
 update: async ({ resource, id, variables, meta }) => {  
 console.log("Overriding the update function");  
  
 // You can either send a request from scratch or use the original function  
 return await dataProvider.update({ resource, id, variables, meta });  
 },  
};

In this example, the update function is overridden. When the update function is called, it will log "Overriding the update function" to the console and then call the original update function. You can replace update with the name of the function you want to override, and implement your own logic as needed. Remember to use myDataProvider instead of dataProvider when passing it to the Refine component:

<Refine dataProvider={myDataProvider} />

<Refine dataProvider={myDataProvider} />

For more information, you can refer to the refine documentation (https://refine.dev/docs/guides-concepts/faq#how-i-can-override-specific-function-of-data-providers). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Now dataProvider property of Refine component says: Type '{ custom: ({ url, method, headers, meta }: { url: any; method: any; headers: any; meta: any; }) => Promise<{ data: any; }>; getList: <TData extends BaseRecord = BaseRecord>(params: GetListParams) => Promise<...>; ... 8 more ...; getApiUrl: () => string; }' is not assignable to type 'IDataContextProvider | IDataMultipleContextProvider | undefined'.

Let me check the knowledge base for you. One moment! :books: ---------------------- The error message you're seeing suggests that the object you're trying to assign to the dataProvider prop of the Refine component doesn't match the expected type. The dataProvider prop expects an object of type IDataContextProvider, IDataMultipleContextProvider, or undefined. The IDataContextProvider and IDataMultipleContextProvider types are interfaces that define the shape of the data provider object. They specify the methods that a data provider should have. Here's an example of what a data provider object should look like:

const dataProvider: DataProvider = {  
 getList: ({ resource, pagination, sorters, filters, meta }) => Promise,  
 create: ({ resource, variables, meta }) => Promise,  
 update: ({ resource, id, variables, meta }) => Promise,  
 deleteOne: ({ resource, id, variables, meta }) => Promise,  
 getOne: ({ resource, id, meta }) => Promise,  
 getApiUrl: () => "",  
  
 // optional methods  
 getMany: ({ resource, ids, meta }) => Promise,  
 createMany: ({ resource, variables, meta }) => Promise,  
 deleteMany: ({ resource, ids, variables, meta }) => Promise,  
 updateMany: ({ resource, ids, variables, meta }) => Promise,  
 custom: ({ url, method, filters, sorters, payload, query, headers, meta }) =>  
 Promise,  
};

const dataProvider: DataProvider = {  
 getList: ({ resource, pagination, sorters, filters, meta }) => Promise,  
 create: ({ resource, variables, meta }) => Promise,  
 update: ({ resource, id, variables, meta }) => Promise,  
 deleteOne: ({ resource, id, variables, meta }) => Promise,  
 getOne: ({ resource, id, meta }) => Promise,  
 getApiUrl: () => "",  
  
 // optional methods  
 getMany: ({ resource, ids, meta }) => Promise,  
 createMany: ({ resource, variables, meta }) => Promise,  
 deleteMany: ({ resource, ids, variables, meta }) => Promise,  
 updateMany: ({ resource, ids, variables, meta }) => Promise,  
 custom: ({ url, method, filters, sorters, payload, query, headers, meta }) =>  
 Promise,  
};

(Source: Refine React Invoice Generator (https://refine.dev/blog/refine-react-invoice-generator-2#refine-s-dataprovider-prop)) If you're seeing this error, it's likely that your data provider object is missing some of these methods, or the methods don't have the correct signatures. Make sure your data provider object includes all the required methods and that they return a Promise. If you're still having trouble, you might find it helpful to refer to the Refine documentation on data providers (https://refine.dev/docs/data/data-provider). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I did spread the original dataProvider like you said so, so the methods shouldn't be missing..

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- You're correct that spreading the original dataProvider should include all the necessary methods. However, the error you're seeing might be due to TypeScript not being able to correctly infer the type of the dataProvider object after you've spread it and added your custom function. To help TypeScript understand the type of your custom data provider, you can explicitly declare it as a DataProvider:

import { DataProvider } from "@refinedev/core";

const myDataProvider: DataProvider = {  
 ...dataProvider,  
 update: async ({ resource, id, variables, meta }) => {  
 console.log("Overriding the update function");  
  
 // You can either send a request from scratch or use the original function  
 return await dataProvider.update({ resource, id, variables, meta });  
 },  
};

import { DataProvider } from "@refinedev/core";

const myDataProvider: DataProvider = {  
 ...dataProvider,  
 update: async ({ resource, id, variables, meta }) => {  
 console.log("Overriding the update function");  
  
 // You can either send a request from scratch or use the original function  
 return await dataProvider.update({ resource, id, variables, meta });  
 },  
};

In this example, myDataProvider is explicitly declared as a DataProvider, which should help TypeScript understand its type. If you're still having trouble, please ensure that your dataProvider object includes all the necessary methods as described in the Refine documentation (https://refine.dev/docs/data/data-provider#methods). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
