Hook Error with array

[sol2010 9]

I am using this hook to get additional notifications when a support department ticket is opened.  However, after upgrade to PHP 8.1 and the new WHMCS version, I am getting an error;

https://github.com/solaceten/WHMCS-Hooks/blob/main/includes/hooks/emergencyticket.php

 

I'm getting an error from the code  ' if (in_array($departmentid, $criticaldept)) { '  (line 26) 
 
Something went wrong and we couldn't process your request.
Please go back to the previous page and try again.

 

TypeError: in_array(): Argument #2 ($haystack) must be of type array, int given in /home/ domain  /public_html/clients/includes/hooks/emergencyticket.php:26

 

Here is the relevent code... why is the array an issue ?

 

function hook_send_emergency_email($vars) {
  
  $criticaldept = 5; // id of emergency department
  $departmentid = $vars['deptid'];
  $company = $vars['companyname'];
    
    if (in_array($vars['deptid'], $criticaldept)) {

Because that's not an array. 
Try: 

$criticaldept = array('5'); // id of emergency department

i get this error

TypeError: in_array(): Argument #2 ($haystack) must be of type array, null given in /var/www/vhosts/

  if (!in_array("error", $result)) {
                logModuleCall("Xtream UI ONE", "Custom Fields", "Custom Fields Created", $custom_fields);
            }

anyone can help me with this?

Since $result isn't defined in the code this was about, your code is likely not the same. Can you show your code?
