[satosa-users] I have a question about operations in satosa.

Hello I'm having a strange error with my Satosa (oidc-to-saml) frontend [satosa.frontends.openid_connect]: invalid client authentication at token endpoint Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/satosa/frontends/openid_connect.py", line 362, in token_endpoint response = self.provider.handle_token_request(urlencode(context.request), headers) File "/usr/local/lib/python3.6/site-packages/pyop/provider.py", line 319, in handle_token_request token_request = self._verify_client_authentication(request_body, http_headers) File "/usr/local/lib/python3.6/site-packages/pyop/provider.py", line 425, in _verify_client_authentication token_request['client_id'] = verify_client_authentication(self.clients, token_request, http_headers.get('Authorization')) File "/usr/local/lib/python3.6/site-packages/pyop/client_authentication.py", line 57, in verify_client_authentication raise InvalidClientAuthentication(client_secret) pyop.exceptions.InvalidClientAuthentication: None The above error repeats over and over again. I'm not sure if it's problem with client_id registration, tokenEndpoint, or Satosa internal settings. Could you tell me how to solve this problem?
