Papermerge / Container Station / QNAP

I have installed Papermerge on the QNAP, and the installation went smoothly. However, I am encountering an issue when trying to log in to Papermerge. I am receiving the message “SyntaxError: Unexpected token ‘<’”. I kindly request assistance with this matter.

It happens when an API ndpoint doesn’t respond as expected and you get an HTML error instead o a json for example. Since I have no idea how that container station on QNAP works, I would recommend trying to share the issue on a QNAP forum.
