### Überschreiben von Request-Validierungs-Exceptions { #override-request-validation-exceptions }

Wenn ein Request ungültige Daten enthält, löst **FastAPI** intern einen `RequestValidationError` aus.

Dann wird der Browser ein HTTP-`OPTIONS`-<abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> an das `:80`-Backend senden, und wenn das Backend die entsprechenden Header sendet, die die Kommunikation von diesem anderen Origin (`http://localhost:8080`) autorisieren, lässt der `:8080`-Browser das JavaScript im Frontend seinen Request an das `:80`-Backend senden.
