Describe the Bug

During crawling I find the following error in my Nextcloud 27.0.2 log:

Not sure if related, but the last time background job ran is always shown as "never" despite them running just fine (I see new photos being tagged):

Expected Behavior

No log error

To Reproduce

Run background job

Debug log

No response

There is a second place where nodeDistance does not seem to be defined:

{"reqId":"Q3PjAyCf9kJWJaGQynOd","level":3,"time":"2023-08-14T16:06:10+02:00","remoteAddr":"","user":"--","app":"PHP","method":"","url":"--","message":"Undefined variable $nodeDistance at /var/www/nextcloud/apps/recognize/lib/Clustering/MstSolver.php#122","userAgent":"--","version":"27.0.1.2","data":{"app":"PHP"},"id":"64edb0387ee20"}

Which PHP version are you running? Debian 11 doesn't have PHP8 by default, right?

[simonspa]

Hi @marcelklehr, this is PHP Version 8.1.22, installed via the regular deb.sury.org repository.

[marcelklehr]

@MB-Finski Any idea why that variable might be undefined there? Doesn't seem to make sense to me

I have the same issue Rocky linux 9.3 PHP 8.2.17 Recognize 6.1.1 Nextcloud 28

using ngxin and php-fpm

[PHP] Error: Undefined variable $nodeDistance at ***/apps/recognize/lib/Clustering/MstSolver.php#122 from ? by -- at 7 avr. 2024, 19:30:47

I can't reproduce this. I believe you that you get this, but I'm gonna call this a fluke for now.
