Debounced input with async resolver

[jodoox]

I've been trying to get a debounced username field work with async validation. So far I've not managed to make it work and I'd appreciate any pointers. Here is a simple example reproducing the issue, the only difference between the two forms being that the async validation callback is debounced (via the use-debounce/useDebouncedCallback hook) or not.

My issue here is that the form validation is late in the debounced version: despite the isValid boolean being received, this does not get reflected on the form's state until the next validation (onBlur / onChange).

Happy to move this to another place (stackoverflow?) if this question does not belong here- the discussions in @hookform/resolvers are closed so I figured I'd ask here.

Did you managed to solve this? The problem is that the debounced function always returns the result of the last invocation (or undefined in the first invocation). I think use-debounce is most suitable for functions that invokes side effects somewhere else.
