jwt.exceptions.ExpiredSignatureError: Signature has expired

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "/code/namex/resources/payment/payment.py", line 435, in post
is_staff = self._is_staff(auth_header)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/code/namex/resources/payment/payment.py", line 340, in _is_staff
return auth_header and validate_roles(jwt, auth_header, [User.STAFF])
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/code/namex/utils/auth.py", line 127, in validate_roles
_jwt._validate_token(token)
File "/usr/local/lib/python3.12/site-packages/flask_jwt_oidc/jwt_manager.py", line 337, in _validate_token
raise AuthError({'code': 'token_expired',

Start by reading namex/resources/payment/payment.py around post and _is_staff, then follow validate_roles in namex/utils/auth.py and the logged flask_jwt_oidc validation path. Reproduce or trace the CREATE request with an expired token and clarify the intended error handling; done should be demonstrated by a focused test and clean expected logging for this case.
