CSOM code is not working after adding custom domain to MS365 Tenant

Question

Hi,

Recently, my organisation added custom domain and user upn also changed according to it. Now, CSOM code is giving error as "The Application ID (AppID) For Which The Service Ticket Is Requested Does Not Exist On The System".

SCRIPT BELOW

Add-Type -Path "D:\CSOM Code Test\Microsoft.SharePoint.Client.dll"
Add-Type -Path "D:\CSOM Code Test\Microsoft.SharePoint.Client.Runtime.dll"

$siteURL = https://XXXX.sharepoint.com/sites/MF

$userId = SVC_SPO.Mig_Acc1@X****

$pwd = Read-Host -Prompt "Enter Password" -AsSecureString

$creds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($userId, $pwd)

$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($siteURL)

$ctx.credentials = $creds

try{

$lists = $ctx.web.Lists   

$list = $lists.GetByTitle("VMs")   

$listItems = $list.GetItems([Microsoft.SharePoint.Client.CamlQuery]::CreateAllItemsQuery())   

$ctx.load($listItems)   

    

$ctx.executeQuery()   

foreach($listItem in $listItems)   

{   

    Write-Host "ID - " $listItem["ID"] "Title - " $listItem["Title"]   

}   

}

catch{

write-host "$($_.Exception.Message)" -foregroundcolor red   

}

Hi @KINTALI SANTOSH KUMAR ,

According to my research and testing ,please try to do a troubleshooting, please check if you have Full Control on Tenant .

You can refer to this document: The Application ID (AppID) For Which The Service Ticket Is Requested Does Not Exist On The System

As a workaround , I suggest you can use the following code to connect to the SharePoint Online :

Add-Type -Path "C:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"  
Add-Type -Path "C:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"  
  
$SiteUrl = "https://xxxx.sharepoint.com/sites/xxx"  
    
#Get Credentials to connect to SharePoint Online site  
$Cred = Get-Credential  
      
#Set up the context  
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteUrl)  
$Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)  
  
  
  
try{  
  
 $lists = $ctx.web.Lists   
 $list = $lists.GetByTitle("test")   
 $listItems = $list.GetItems([Microsoft.SharePoint.Client.CamlQuery]::CreateAllItemsQuery())   
 $ctx.load($listItems)   
        
 $ctx.executeQuery()   
 foreach($listItem in $listItems)   
 {   
     Write-Host "ID - " $listItem["ID"] "Title - " $listItem["Title"]   
 }   
  
}  
  
catch{  
  
 write-host "$($_.Exception.Message)" -foregroundcolor red   
  
}
