Map error in useQuery and useMutation

[V1OL3TF0X]

Hi, I was wondering if there is an option to add a prop similar to useQuery's select to enable mapping over errors in useQuery (and other queries too) and useMutation. The only real alternative I see is to catch and rethrow it, as onError uses the persisted state, and this is not ideal since I don't need to build the exception stack or w/e just to map over a value. It would be really helpful since in our app we have a special useApiMutation hook that splits error handling into three distinct parts - BadRequest errors, NotFound errors and Remaining errors, and I would like to hold only the final message in the error state of the mutation, to not have to move mapping of values into react's dependency tracking.

Thanks for answers!

add try/catch inside the queryFn / mutationFn and only re-throw the error you want after you’ve handled it.
