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
