Do we have the latest, maintained Okta SAML SSO sample I can examine?

The current Github project, GitHub - oktadev/okta-spring-boot-saml-example: Spring Boot, SAML, and Okta , was originally maintained by Matt Raible, who now no longer works at Okta.

There is an issue with the project sample’s code, where it couldn’t handle Okta’s initial OPTIONS request before proceeding with the actual POST SAML request. I reported this issue on the project, but because the project is now stale, I closed the issue.

What’s the proper way of handling the Okta’s OPTIONS request? Do we ignore it, and keep seeing the “No relying party registration” error? Or is there a better way of fixing the problem?
