MutationKey null when using persistQueryClient

Hi, I am using persistQueryClient for caching mutations and queries when the user is offline. It works well for queries, but not for mutations. When using the custom hook

useCreateTodo

useCreateTodo

, I am getting a mutationKey of [null]. However, if I import the

useMutation

useMutation

hook and use it like this:

useMutation({mutationKey:['create-todo']})

useMutation({mutationKey:['create-todo']})

, it works when I restarts the app.

I already have a mutationDefaults

queryClient.setMutationDefaults(['create-todo'], {
  mutationFn: createTodo
});

queryClient.setMutationDefaults(['create-todo'], {
  mutationFn: createTodo
});
