I am trying to integrate BoxyHq-saml provider into a Nextjs15 app with next-auth version 5.0.0-beta.25. To test the integration, I used the Mock Saml xml metadata to create a saml connection. When I try to login, I am successfully redirected to their login page, which sends me back to localhost. Then the following happens:
