EwoutV commented 3 days ago

From a fresh installation, the local instance of Spring Boot gives the following error upon start:

This does not break the backend, but needs investigation.

We've externalized the SAML dependency to another service a long time ago, so the saml dependency can likely be removed from the main backend - which would likely solve this problem.
