No app in context

Nextcloud version: 11.0.4.1
Operating system and version: Raspbian GNU/Linux 8 (jessie)
Apache or nginx version: nginx 1.6.2
PHP version: 5.6.30
Is this the first time you’ve seen this error?: Yes

Can you reliably replicate it? (If so, please outline steps): No, just uploaded files from NC desktop client to NC.

The issue you are facing:

I see a huge amount of errors in my logfile telling me “no app in context”.

I yesterday started to create a fresh instance of Nextcloud and uploaded all my files during the first sync using NC desktop client. I am using “external” data directory.

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

<?php

);

The output of your Apache/nginx/system log in /var/log/____:

empty log

Any idea how to get this fixed?

Seems to be related to Activity app. Once I disabled it in App-Store the messages disappeared. But this is just a workaround. Is there a solution for this? Or where shall I address it to?

Kind regards
