Persist error on refetch

[Sagie501]

Hi!

I think it would be very useful to add persistError property to the useQuery options.
Today if I had error returned from my query and then the query refetched (doesn't matter why maybe explicit refetch, maybe refetchInterval or any other reason) the error is set to null and isError to false.
Adding persistError property and set it to true will keep the error state and isError true.

I would be happy if you share what you think about it!
Thanks!

Error is not serializable to json so per default, this wouldn't work. You'd need to provide s custom serializer like superjson

@TkDodo Although it's a bit old do you have an idea what to do to overcome this issue?
I have the same issue as presented here:
