Azure function app stuck because of paging nextLink

Question

I created an Azure function where I try to get all the AAD groupmembers. This timerjob needs to run once a day. When I do a test run I see in the logging it iterates a couple of time in the nextLink paging. But then it stuck without an error. I already increase the timeout to 10 minutes, but I still have the same problem.

When I run this script local on my machine it works fine. I expect it should iterate 127 times and get 12757 items. test run

When I go to the monitor logging I dont see the session which was stuck. monitoring logging

using namespace System.Net

   Write-Output "Get items from MS Graph"
   $token = (Get-AzAccessToken -ResourceUrl "https://graph.microsoft.com/").Token
   $authHeader = @{Authorization = "Bearer $token"}
    
    # #endregion
    
    # #region main proces

    $allPages = @()
    $items = (Invoke-RestMethod -Method 'Get' -Uri 'https://graph.microsoft.com/v1.0/groups?$top=999&$expand=members' -Headers $authHeader  -ContentType 'Application/Json') 
    $allPages += $items.value

    $index = 0
    if ($items.'@odata.nextLink') {
            do {
                  $index++
                  "Index counter: $index"

                  $token = (Get-AzAccessToken -ResourceUrl "https://graph.microsoft.com/").Token
                  $authHeader = @{Authorization = "Bearer $token"}

                  $items = (Invoke-RestMethod -Method 'Get' -Uri $items.'@odata.nextLink' -Headers $authHeader  -ContentType 'Application/Json')
                  $allPages += $items.value
             } until (
