Cannot invoke "org.springframework.security.core.Authentication.getName()" because "authentication" is null

While trying to save the User I'm getting this error, I've tried anything from changing my code to be completely like yours...

I want to mention that I'm currently implementing it in the REST API because I don't have access to the front-end, so yeah I want to redirect to URL api/hello-world for now if that might be a problem too
