The serverValidate method returns the old values as part of the error, which get merged back over your changed state in transform.
Unsure why it is done this way but you can delete state.values in the transform method as a short-term fix.

Why does that prevent the form from receiving user input?
MVaik commentedon Mar 29, 2025
The form receives user input, the error result just overwrites it.

No, brother. That’s why I say “wait for the action to complete”. Try it.

Alright I get what you meant, but the reason is the same, the error result that has empty fields gets merged over state on first keypress for some reason.

This looks to be completed in #1890, so I'm going to close this issue. If the problem persists please reopen it 😊
