Bir request geçersiz veri içerdiğinde, **FastAPI** içeride `RequestValidationError` raise eder.

Ve bunun için varsayılan bir exception handler da içerir.

Override etmek için `RequestValidationError`’ı import edin ve exception handler’ı `@app.exception_handler(RequestValidationError)` ile decorate edin.

Exception handler, bir `Request` ve exception’ı alır.
