Conflict with OAuth2 authentication provider

Thanks, @amr_alsayd.

The patch is working for me. Thanks for that.

I hope this change gets approved.

This patch would break all existing sites, so it is not acceptable.

Clearly we already support the 'JWT-Authorization' header.

Since Oauth2 may be using a JWT as the token, I'm not sure there is an easy way to make these compatible.

A partial fix could be to change the method \Drupal\jwt\Authentication\Provider\JwtAuth::getJwtFromRequest() and make the regex more specific to the pattern of a JWT so it would ignore some other kind of token being used by OAuth2

Something like this - passes a quick check, and maybe the minimum size of each segment should be larger.

Is this the module that you see conflicting? https://www.drupal.org/project/simple_oauth →

A further approach could be a setting in settings.php to change the default header (or default and fallback headers) that would come via \Drupal\Core\Site\Settings which we are already injecting into this class

This seems more-or-less duplicate to this bug reported several years ago:
#3189827: Access denied with bearer token on oauth/debug when Jwt is installed →
