We have upgraded our Spring-boot Java application with JDK 17 together with Spring-boot latest version. that's also included upgrading all of our external dependencies in order to clean up any potential vulnerabilities.
Everything seemed to work well. the application compiles and starting up and also all our components tests are running with flying colors.
The only problem we are having is that we cannot get any REST call anymore to every public entry access point we are having in each of our rest controllers.Every attempt is getting results with the following error:
{"type": "about:blank","title": "Not Found","status": 404,"detail": "No static resource .","instance": "/","properties": null}Does anyone have any clue why this is happening and how to resolve it?
