      Create a new issuer through the administration site with the following parameters (OpenId Connect Test server):

         Name: Test

         Client ID: user

         Client Secret: password

         Service base URL: https://mitreid.org/

      Leave the reset as it is. Logo URL must be empty!

      The issuer should be saved without an error. (Currently the Error from the Description is thrown)

      Unfortunately, the test server above has no favicon.ico. However, the error when creating the issue is gone.

However, the error when creating the issue is gone.  

      In the function guess_image() of the lib/classes/oauth2/api.php:350 there is a call to get the property 'discoveryurl' of an issuer. However, this property is never defined for an issuer and therefore throws the exception:

      coding_exception: Coding error detected, it must be fixed by a programmer: Unexpected property 'discoveryurl' requested

      This problem does not occur in core, since all predefined issuers have already a predefined image. So this code within

      if (empty($issuer->get('image'))) {

      is never called.
