Internal 500 on .findAll()

[robertlocskai]

Hey, I just made a class called Project, have a repository, controller and a service. I will attach these below but first I'll try to explain my issue. So I basically made a project controller where I wanna create, and findbyid, findbyownerid and list all projects. (First i just wanted create and findbyownerid, i added the others to test). My issue is that the create works fine with the .save(). It saves it in mongodb all fine. But on any get request i get a 500 Internal Error.

This is the log for getallprojects for example:

My Project class:

	return findById(id).orElse(null);

My project service:
`import java.util.List;

    	return new ResponseEntity<>(HttpStatus.UNAUTHORIZED);
   
    List<Project> projects = projectRepository.findAll();
    
    return new ResponseEntity<List<Project>>(projects, HttpStatus.OK);
}

public ResponseEntity<Project> getProject(String id) {
	if(id != null) {
		Project project = projectRepository.getById(id);

		return new ResponseEntity<Project>(project, HttpStatus.OK);
	}
	else
		return new ResponseEntity<>(null, HttpStatus.OK);
	
	
}

public ResponseEntity<List<Project>> getAll() {
	return new ResponseEntity<>(projectRepository.findAll(), HttpStatus.OK);
}

}`

And I'm not attaching the controller since its just a return of the service methods.

Any help is appreciated but im literally going insane, i have no idea what is wrong, I've tried everything I could think of.

Thanks

Also I already have other classes like "Plan" which has the same findById too, and it works all good. Spring boot makin me mad for real rn

This looks like you need to make sure to configure the compiler to use the -parameters flag.
See also Spring Framework 6.0 Release Notes.

If that does not work and you'd like us to spend some time investigating, please take the time to provide a complete minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem.

Well it was an issue with lombok and eclipse. Switched to IntelliJ, cleaned up stuff and it just suddenly worked lol.
