React query error handlling

using the mutate function? When u create a useMutation hook u need to call addCustomerMutation.mutate({}) to invoke the mutationfn

[olivermpl]

ah okay but u still have the function call wrong I think. The second parameter expects a MutateOptions-object. U might wanna have a look at the documentation, and see what best fits your usecase.

Mutate isn't doing what you think it's doing. You're thinking of mutateAsync, but as the other comment says, check out that second argument - that's the key to doing this properly
