I installed a fresh copy of Drupal 8 using Docker Compose. I then installed OAuth2 Server and when I tried to enable it, it crashed with this error:

Fatal error: Interface 'OAuth2\OpenID\Storage\AuthorizationCodeInterface' not found in /var/www/html/modules/oauth2_server/src/OAuth2StorageInterface.php on line 19

You probably didn't install with composer, did you?
