 [2019-12-19 13:42:22,579] Not valid client [(ERROR) oidc_op.views.service_endpoint:143]
 ERROR:oidc_op.views:Not valid client

JWTConnect-python-oidcrp.flask_rp doesn't handle this behaviour and goes in exception.

where exception whould be handled here:

 JWTConnect-Python-OidcMsg/src/oidcmsg/message.py", line 282, in from_dict
     for key, val in dictionary.items():
 AttributeError: 'str' object has no attribute 'items'
