Hello @blippercop
Could you detail step by step?
Could you give a minimalist sample in order to reproduce?
Could you post the log files: php-errors.log, sql-errors.log, TicketCleaner.log (to get this one you must activated GLPI debug mode)?
Thank you,
Regards,

I will try to add information, but I was not sure myself what was causing this.

Now I know this issues happens when an email is pulled that contains an inline picture.

This issue is not(!) logged in the php-error log etc.
Loading of sha1 files from '/var/www/helpdesk/plugins/ticketcleaner/pictures' into DB done.
2024-02-07 09:16:01 [-server]
Ticket: 'test'
File: '/var/www/uem/files/_tmp/pastedgraphic-1.png' type: 'image/png' sha1: 'f702b3acf4a0f470961fa6080c5383e304f18697' deleted: 'False'

it is logged by the crontab and not the GLPI logs
So all outputs of the crontab are logged on my system - this will show normally no output except for some php warnings

I will try to analyze further.

$res = $DB->request('glpi_plugin_ticketcleaner_picturehashes_lastupdate');
if ($res->numrows() > 0) {
//$row = $DB->fetch_array($res);
$row = $res->next();
$lastupdate = $row['lastupdate'];
}

after $res->next(); the $row is null.
is $row = $res->current(); an option? It returns the correct value.
