I can't access anything other than the json response in a redux toolkit mutation api. Please don't suggest to use onSuccess

Steps or Code to Reproduce

endpoints: (builder) => ({ sendDetails: builder.mutation({ query: ({ title, languages, errorMessage, steps, lang }) => ({ url: "/", method: "POST", body: { title, lang }, }), invalidatesTags: [{ type: 'other', id: 'singleton' }], transformResponse: (response) => { console.log('response', response); return response; }, }), }),

Suggested Fix

Accessing response headers in Redux Toolkit without using onSuccess

In Redux Toolkit, while using createAsyncThunk or createSlice to make API calls, it's not straightforward to directly access the response headers. However, you can still achieve this by customizing your API request setup a bit. Here are the steps you can follow:

  1. Modify the API call to return both response data and headers:

    • Update your API endpoint declaration to return an object that includes both the response data and headers.
  2. Accessing response headers in the component:

    • Once you receive the response from the Redux action, you can access the headers from there.

Here is an example of how you can modify your code:

javascript

In your React component where you dispatch the action, you can access the headers as follows:

javascript

By making these changes, you should now be able to access both the response data and headers in your Redux logic.
