Haystack error when opening tickets (occassionally)

[pKris 0]

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:
