There could be several reasons why you're not getting data in the

onSuccess

onSuccess

onSuccess

onSuccess callback. Here are a few possibilities based on the information provided in the extracts:

Incorrect Hook Usage: If you're using the
```
useForm
```
useForm
```
useForm
```
useForm
hook and expecting data to be returned after a mutation (create, update, delete), you should use the
```
onMutationSuccess
```
onMutationSuccess
```
onMutationSuccess
```
onMutationSuccess
callback, not
```
onSuccess
```
onSuccess
```
onSuccess
```
onSuccess
. The
```
onSuccess
```
onSuccess
```
onSuccess
```
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.
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
```
onMutationSuccess
```
onMutationSuccess
```
onMutationSuccess
callback from
```
useForm
```
useForm
```
useForm
```
useForm
doesn't return data when using the Supabase data provider.
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 (ask-any-questionHow to fetch the data back present in the network preview after creating with hlp of useForm).

If you're still facing issues, it would be helpful to provide more context or code snippets to better understand the problem.

why I can get only undefined?

There could be several reasons why you're getting

undefined

undefined

as a result. Here are a few possibilities based on the information provided in the extracts:

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)
```
JSON.parse(undefined)
```
JSON.parse(undefined)
```
JSON.parse(undefined)
, it will produce an error because
```
undefined
```
```
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).
Undefined Query Data: If the data returned by your query function is
```
undefined
```
```
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.
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
```
tokens
```
tokens
```
tokens
of an undefined object (like
```
undefined.tokens
```
undefined.tokens
```
undefined.tokens
```
undefined.tokens
), you'll get a
```
TypeError: Cannot read properties of undefined (reading 'tokens')
```
TypeError: Cannot read properties of undefined (reading 'tokens')
```
TypeError: Cannot read properties of undefined (reading 'tokens')
```
TypeError: Cannot read properties of undefined (reading 'tokens')
error. This was discussed in a Discord support thread (ask-any-questionCannot read properties of undefined (reading 'tokens')).

If you're still facing issues, it would be helpful to provide more context or code snippets to better understand the problem.

The

data.data

data.data

data.data

data.data being

undefined

undefined

could be due to several reasons. Here are a few possibilities:

Response Structure: The structure of the response from your server might not be as expected. The
```
data.data
```
data.data
```
data.data
```
data.data
implies that the response is an object with a
```
data
```
```
data
```
property, which itself is an object containing the actual data. If your server is not structured this way,
```
data.data
```
data.data
```
data.data
```
data.data
would be
```
undefined
```
```
undefined
```
. You should check the structure of the response from your server.
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
```
data.data
```
data.data
```
data.data
being
```
undefined
```
```
undefined
```
. You should check your server logs to see if there are any errors.
Network Error: If there's a network error and the request to the server fails,
```
data.data
```
data.data
```
data.data
```
data.data
would be
```
undefined
```
```
undefined
```
. You should check your network requests to see if they are successful.

In your

onSuccess

onSuccess

onSuccess

onSuccess callback, you're checking if

data.data

data.data

data.data

data.data exists before proceeding with other operations. This is a good practice as it prevents errors if

data.data

data.data

data.data

data.data is

undefined

undefined

. However, you might want to add some error handling or logging to understand why

data.data

data.data

data.data

data.data is

undefined

undefined

.

Here's an example of how you can add some logging:

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')
  } else {
    console.log('data.data is undefined', data);
  }
},

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')
  } else {
    console.log('data.data is undefined', data);
  }
},

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')
  } else {
    console.log('data.data is undefined', data);
  }
},

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')
  } else {
    console.log('data.data is undefined', data);
  }
},

This will log the entire

data

data

object when

data.data

data.data

data.data

data.data is

undefined

undefined

, which might help you understand why it's

undefined

undefined

.

@kapa.ai I can insert record but get undefined

----------------------
If you're able to insert a record but getting

undefined

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

create

create

create operation.

In your

createMutate

createMutate

createMutate

createMutate function, you're expecting the created record to be in

data.data

data.data

data.data

data.data in the

onSuccess

onSuccess

onSuccess

onSuccess callback. If your server or data provider doesn't return the created record,

data.data

data.data

data.data

data.data would be

undefined

undefined

.

Here's the relevant part of your code:

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')
  }}
}},

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')
  }}
}},

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')
  }}
}},

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')
  }}
}},

You should check your server or data provider documentation to see if they return the created record after a

create

create

create

create operation. If they don't, you might need to make an additional

read

read

read

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.
