Hi @yasuaki_jp. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

There could be several reasons why you're not getting data in the
onSuccess callback. Here are a few possibilities based on the information provided in the extracts:
1. Incorrect Hook Usage: If you're using the useForm hook and expecting data to be returned after a mutation (create, update, delete), you should use the onMutationSuccess callback, not onSuccess. The onSuccess callback is used for fetching data, not mutations. You can refer to the useForm documentation (https://refine.dev/docs/api-reference/antd/hooks/form/useForm/#onmutationsuccess) for more details.
2. Data Provider Issues: If you're using a specific data provider like Supabase, there might be issues with the provider itself. For instance, there's an open issue (https://github.com/refinedev/refine/issues/5679) where the onMutationSuccess callback from useForm doesn't return data when using the Supabase data provider.
3. Incorrect Action Specification: In some cases, you might need to specify the action (create or edit) for the data to be returned correctly. This was mentioned in a Discord support thread (https://discord.com/channels/837692625737613362/1163445501006454824).
If you're still facing issues, it would be helpful to provide more context or code snippets to better understand the problem.

@kapa.ai
why I can get only undefined?
Let me check the knowledge base for you. One moment! :books:
----------------------
There could be several reasons why you're getting
undefined as a result. Here are a few possibilities based on the information provided in the extracts:
1. Parsing Non-JSON as JSON: If you're trying to parse something that is not JSON as JSON, you'll get an error. For example, if you try to execute JSON.parse(undefined), it will produce an error because undefined is not JSON. This was explained in a blog post on the refine.dev website (https://refine.dev/blog/unexpected-token-in-json-at-position-0-error#what-does-the-unexpected-token--in-json-at-position-0-error-mean).
2. Undefined Query Data: If the data returned by your query function is undefined, you'll get an error. This was reported in a GitHub issue (https://github.com/refinedev/refine/issues/3837) where the user was trying to get user identity data.
3. Accessing Undefined Properties: If you're trying to access a property of an undefined object, you'll get an error. For example, if you're trying to access tokens of an undefined object (like undefined.tokens), you'll get a TypeError: Cannot read properties of undefined (reading 'tokens') error. This was discussed in a Discord support thread (https://discord.com/channels/837692625737613362/1197141532885659658).
If you're still facing issues, it would be helpful to provide more context or code snippets to better understand the problem.

@kapa.ai
data.data always undefined when you success.
createMutate(
{
resource: 'temp_products',
values: {
name,
..._defaultValues,
storage_instructions,
jsf_ids: selectedJsfIds,
expiry_days,
msrp,
remark,
last_updated_user_id: user?.id,
created_user_id: user?.id,
images: imagePaths ? imagePaths : [],
},
},
{
onSuccess: async (data, variables, context) => {
console.log(data, variables, context, 'dataaa')
if (data.data) {
await createReview(data.data.id, rateValue, review)
await createProductsPlans(data.data.id, selectedPlansIds)
list('temp_products')
}
},
onError: (error) => {
console.error('error', error)
},
},
)

The
data.data being undefined could be due to several reasons. Here are a few possibilities:
1. Response Structure: The structure of the response from your server might not be as expected. The data.data implies that the response is an object with a data property, which itself is an object containing the actual data. If your server is not structured this way, data.data would be undefined. You should check the structure of the response from your server.
2. Server Error: If there's an error on the server-side while processing the request, the server might not be returning any data, resulting in data.data being undefined. You should check your server logs to see if there are any errors.
3. Network Error: If there's a network error and the request to the server fails, data.data would be undefined. You should check your network requests to see if they are successful.
In your onSuccess callback, you're checking if data.data exists before proceeding with other operations. This is a good practice as it prevents errors if data.data is undefined. However, you might want to add some error handling or logging to understand why data.data is undefined.
Here's an example of how you can add some logging:
This will log the entire data object when data.data is undefined, which might help you understand why it's undefined.

@kapa.ai I can insert record but get undefined
Let me check the knowledge base for you. One moment! :books:
----------------------
If you're able to insert a record but getting
undefined in the response, it could be due to the way your server or data provider is set up. Some servers or data providers might not return the created record after a create operation.
In your createMutate function, you're expecting the created record to be in data.data in the onSuccess callback. If your server or data provider doesn't return the created record, data.data would be undefined.
Here's the relevant part of your code:
You should check your server or data provider documentation to see if they return the created record after a create operation. If they don't, you might need to make an additional read request to get the created record.
If you're still facing issues, it would be helpful to provide more context or code snippets to better understand the problem.
