Haystack error when opening tickets (occassionally)

[pKris]

Hey all!

We recently upgraded to WHMCS 8.6, and all is well except for a few issues.

Occasionally a ticket will throw an error when opening it, this ticket could be brand-new or days old with many replies in it:

TypeError: in_array(): Argument #2 ($haystack) must be of type array, null given in /var/www/html/ponyboy/supporttickets.php:0
Stack trace:
#0 /var/www/html/ponyboy/supporttickets.php(0): in_array()
#1 {main}\]

I can still access the ticket via the WHMCS mobile app, it's just the browser that complains.

Same, facing this issue too.

Are you able to reproduce the error by doing specific steps? Giving all information possible will most likely result in a quick fix from WHMCS.

Sadly no, it is an issue that may happen once in a blue moon - we could have a ticket open with a customer and be communicating back and forth on it for days when all of the sudden this pops up.

That specific error just seem like it would happen in a very specific case.
Does the client attach anything? Are they trying to add a CC?

Also, does it happen on 8.6.1 as well?

Hi all,

I can confirm this issue was resolved in v8.6.1:

Hello there

Sorry for reviving this post

This happened to me recently with WHMCS 8.7.3 and PHP 8.1

It happened when a user opened a ticket through an email and between the round trip emails they added 2 people from the organization to the ticket and that is when the error appeared.
Whenever the recipient of the email is more than one person and does not have permissions in the ticket, whmcs throws me the error.
To solve it, we proceeded to register the 2 people of the organization as part of support and with permissions in the ticket office.

After that I stop throwing errors and I manage to import the emails correctly.
Another problem that this generated is that every time the email piping cron was executed, it imported again the same emails that were throwing an error.

Hope this can help someone experiencing the same thing
