500 Error after creating sidebar hook from WHMCS documentation

[neaweb6]

Hey guys, I am replacing all of the support links in WHMCS to direct to my Kayako system. I changed the navigation links on the client area using a custom hook from the WHMCS documentation. This worked fine and here's the hook file:

 

<?php
// Call client area menu
use WHMCS\View\Menu\Item as MenuItem;

// Changes the Support > Tickets child menu text and URL
add_hook('ClientAreaPrimaryNavbar', 1, function (MenuItem $primaryNavbar)
{
   $navItem = $primaryNavbar->getChild('Support');
   if (is_null($navItem)) {
       return;
   }

   $navItem = $navItem->getChild('Tickets');
   if (is_null($navItem)) {
       return;
   }

   $navItem->setLabel('My Conversations');
   $navItem->setUri('https://support.neawebservices.com/conversations');

});

// Changes the Open Ticket parent menu and url
add_hook('ClientAreaPrimaryNavbar', 1, function (MenuItem $primaryNavbar)
{
   $navItem = $primaryNavbar->getChild('Open Ticket');
   if (is_null($navItem)) {
       return;
   }

   $navItem->setLabel('Start a Conversation');
   $navItem->setUri('https://support.neawebservices.com/conversation/new');

});

// Removes the Knowledgebase child menu from the Support parent menu
add_hook('ClientAreaPrimaryNavbar', 1, function (MenuItem $primaryNavbar)
{
   if (!is_null($primaryNavbar->getChild('Support'))) {
       $primaryNavbar->getChild('Support')->removeChild('Knowledgebase');
   }
});
?>

 

I followed the documentation to change the Support sidebar that shows up using the same method, but I am getting a 500 error after submitting the changes. Here's the hook I am using:

 

<?php

use WHMCS\View\Menu\Item as MenuItem;

add_hook('ClientAreaPrimarySidebar', 1, function(MenuItem $primarySidebar)
{
   $primarySidebar->getChild("Support")
       ->getChild("Support Ticket")
       ->setLabel("My Conversations");
});
?>

you need to check if the requested item is not NULL first before performing any actions

 

<?php

use WHMCS\View\Menu\Item as MenuItem;

add_hook('ClientAreaPrimarySidebar', 1, function(MenuItem $primarySidebar)
{
   if (!is_null($primarySidebar->getChild("Support"))){
       if (!is_null($primarySidebar->getChild("Support")->getChild("Support Ticket"))){
               $primarySidebar->getChild("Support")
               ->getChild("Support Ticket")
               ->setLabel("My Conversations");
       }
   }
});
