When doing a simple GET request through your browser to, i.e. https://www.scrumpoker.online/api/session/create the error message includes the full query which also reveals a tablename and its fieldnames.
While it is no high risk directly, IMHO it's better not to reveal this kind of information to the outside world. Maybe you should look into some general handling of these kinds of errors which still provides the necessary information to the end-user, but no technical details.
