Calendar "Internal Server Error"

🍱 Features & apps 📆 Calendar

Hi!
I have a NC instance up and running and everything works good so far. No errors in nginx/error.log except that calendar is not working. I get a “Internal Server Error” everytime I click the Calendar icon. This is the nextcloud log:

Any ideas on that? Every other logs i looked up have no errors…

Kind regards!

Looks like a general problem with Nextcloud server. Could you search Issues · nextcloud/server · GitHub for anything known?
Argument 1 passed to OC\\Files\\SimpleFS\\SimpleFolder::__construct() must implement interface OCP\\Files\\Folder, instance of OC\\Files\\Node\\File given is the error.

From the trace I get that Nextcloud requests a folder and receives a file.

Thank you, that helped a lot! Indeed there was a corrupted file called „calendar“. I deleted the file, created a new folder and rum the occ for rebuilding the apps. Now it works all fine:) Thank you:)
