mod_auth_openidc

When I'm trying to reach the "exampleresource" resource by clicking on the Link https://localhost:8443/exampleresource, my Browser correctly redirects me to the Authentication page. In the meantime, (without having inserted any kind of credentials) in the /var/log/apache2/error.log appear this long sequence of logs (shown below). After attempting to authenticate myself on the Browser (by inserting Username & Password in the form) it shows me an "Invalid credentials" error. Can anyone help me with this issue?

My /etc/apache2/sites-available/default-ssl.conf:
