Designer Authentication with OpenID from Microsoft Entra

I am trying to setup MS Entra with Open ID as an Identity Provider. I got Gateway login working successfully but when I try to sign into our gateway with Designer Authentication Strategy set to Identity Provider it redirects me to my organizations login page but then upon attempting to log in I get an Internal Server Error.

I am trying to set this up on a local gateway first so my redirect URI is just localhost:8088. This works with the gateway but not with the designer and I’m not sure if this is part of the issue. I double checked the Role requirements and those show up in the Test Login on the gateway so I do have the correct permissions when I sign in on the gateway so I don’t think that is the issue.
