Is it possible to keep errors cached while refetching?

[manuel-plavsic]

It seems impossible to me to refresh on an error state. I would like the error to stay cached and the query to update in the background (like with valid data).

I tried setting multiple different options; however, nothing seems to suit my use case. If I refresh on an error then isRefreshing is always false and isLoading is always true. I would prefer to display a spinner next to the error (using {query.isRefetching}) instead of reloading everything...

no, this isn't really possible. We don't keep "stale errors" around. If you want that, you need to copy the error to a separate state.

Error Boundaries work kinda the same way: You show the error boundary, which unmounts the component. Then, the user clicks "retry", which unmounts the boundary and mounts the component again. At that point, you'll get a loading state again.
