Are the errors in onSuccess callback are catch ?

Hello everyone, I have a pretty simple question but i can't find the answer. Imagine i have something like that:

useMutation({
    mutationFn: (newComment) =>
      axios.post(`/posts/${id}/comments`, newComment),
    onSuccess: () => {
      // ✅ refetch the comments list for our blog post
      queryClient.invalidateQueries({ queryKey: ['posts', id, 'comments'] })
    },
  })

useMutation({
    mutationFn: (newComment) =>
      axios.post(`/posts/${id}/comments`, newComment),
    onSuccess: () => {
      // ✅ refetch the comments list for our blog post
      queryClient.invalidateQueries({ queryKey: ['posts', id, 'comments'] })
    },
  })

invalidate could throw an error if for whatever reason it failed no ? And in this case, is the error catch or should wrap the invalidateQueries inside a try/catch ? Thanks for your help 🙂

invalidateQueries doesn't throw errors, so no try/catch needed

oh ok x) i was not sure about that, thanks for your response i was thinking that beacause in type definition invalidateQueries return Promise<void> so i assumed it could throw ok i see, it only throw if i pass throwOnError: true

Yeah it does .catch(noop) per default
