Nextcloud Office is not loading

Hey, I installed Nextcloud office v8.2.1 on a Nextcloud Docker container with docker image from Linuxserver. I also used the built in code server with Nextcloud. However, whenever I try to open a file with it, it get’s stuck on Loading screen. Upon inspecting the console I get the following error.

Hi @RitZz,
Please provide the logs as opposed to screenshots. Docker configuration info if using compose would also be helpful since the issue likely stems from misconfiguration. You are missing the required support template. Please fill this form out and edit into your post.

This will give us the technical info and logs needed to help you! Thanks.

Might be easier to ask linuxserver forum support directly and link back here since they packaged it.
