Problem Statement
How should you handle errors in async operations with createAsyncThunk?
Explanation
Handle errors in createAsyncThunk by using try-catch blocks in your payload creator to catch exceptions, then return rejectWithValue with error data to provide custom error payloads instead of the default rejected action. In your slice's extraReducers, handle the rejected case to store error information in state, optionally including error messages, status codes, or validation errors from the API response. You can also use the thunkAPI.rejectWithValue to pass structured error data that components can use to show specific error messages, implement retry logic using the thunkAPI.dispatch, or handle errors globally in middleware to show notifications or log to error tracking services.
