Hi,

We had the same issue, all of a sudden the counts started showing zeroes. We tracked it down to a ticket where the subject had been written to the database as null, and some javascript which was trying to truncate the subject to < 300 characters. The js couldn't truncate null, so it crashed.

We fixed it by editing two files:

Change line 409 of vendor/uvdesk/mailbox-component/Services/MailboxService.php

From:
'subject' => $emailParser->getHeader('subject') != false ? $emailParser->getHeader('subject') : null,

To:
'subject' => $emailParser->getHeader('subject') != false ? $emailParser->getHeader('subject') : "No Subject",

This writes "No Subject" to the subject column in the database instead of null.

Then change line 1361 of vendor/uvdesk/core-framework/Resources/views/ticketList.html.twig

From:
<%- subject && subject.length <= 300 ? subject : subject.substr(0, 300) + '...'  %>

To:
<%- subject && subject.length <= 300 ? subject : (subject == null ? 'No Subject' : subject.substr(0, 300) + '...')  %>

This prevents the ticket page from crashing if there are any existing tickets with null subjects, and will display "No Subject" instead.

My apologies, the original line is the one listed as line 410 in that file:

$mailData['subject'] = $parser->getHeader('subject');

I must have a different version of that service file on my server.

The appropriate change for that version of the file would be to change the line above to:

$mailData['subject'] = $parser->getHeader('subject') !== null ? $parser->getHeader('subject') : 'No Subject';
