Hello everybody. I have a problem. In Nextcloud logs error

Error PHP Undefined index: urlsrc at /…/apps/richdocuments/templates/documents.php#6
Error PHP Undefined index: token at /…/apps/richdocuments/templates/documents.php#5

Does anyone have a solution?

Nextcloud v 18.03
Collabora Online v3.5.3
PHP v 7.2.31

Does anyone have a solution?

I’ve exactly the same problem with Nextcloud 18.0.3 running inside Docker with LibreOffice Online 6.2-6 connected via Collabora App 3.7.3.

Any solution oder reason for this error known?

Same here:

Undefined index: urlsrc at /var/www/html/apps/richdocuments/templates/documents.php#6
Undefined index: token at /var/www/html/apps/richdocuments/templates/documents.php#5

same error with nextcloud 19 and latest collabora version from ubuntu20.04
