GET /apps/mediadc/

I'm experiencing the exact same issue. At least for me this issue seems to be related to an issue in cloud_py_api as I can't install the cloud_py_api helper library because of linked error.
Im on Nextcloud 27.0.0 inside a docker from linuxserver-team.

EDIT: Am i maybe missing something?

[rumexcrisp]

Seems like i resolved the error. I did the following steps:

1. Linuxserver-team provides mods with their docker containers. Install mediadc mod by adding docker variable DOCKER_MODS with value linuxserver/mods:nextcloud-mediadc, e.g.: docker run -eDOCKER_MODS="linuxserver/mods:nextcloud-mediadc"
2. Install cloud_py_api and mediadc app from nextcloud appstore.
3. I got an error specifying that the DB table oc_cloud_py_api was not found. This error came from another wrong setting inside oc_appconfig, i guess due to a migration error during a previous update (not sure how this works exactly).
4. Delete the apps, not just deactivating.
5. On your own risk and with a complete db backup: Delete entries relating to your problem-app, e.g. for cloud_py_api the keys enabled, installed_version and types.
6. Continue from step 2. I had to redo steps 2-5 for mediadc as well.

Hope someone will find this helpful as it helped me get this sorted.
