The dev parameter is False, but the pydantic check fails and returns 500 anyway

The request returns only content:An error occurred while handling an error

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

I myself wrote a simple demo that did not appear in this situation, the dev parameter returns 500 for True, 400 for False and pydantic check exception information, which is as expected, want to know when this happens?
