Powershell Invoke-RestMethod error 400

I’ve been looking for a script to identify stale Azure AD users. Trying to run the example at https://github.com/azure365pro/AzureAD_Inactive_Users/blob/main/AzureAD_Inactive_Users.ps1. Does it work in a GCC High tenant? I’ve modified the URLs to reference the “.us” suffix but getting an error when the script runs the line below.

$ExpiredUsers = (Invoke-RestMethod -Headers @{Authorization = "Bearer $($token)"} -Uri $LoginUrl -Method Get).value

The error message is:

Invoke-RestMethod : The remote server returned an error: (400) Bad Request.
At C:\xxx\Documents\Scripts\AzureAD_Inactive_Users.ps1:58 char:18

Hi,

Please make sure the URL you are trying to access is valid. You can also try to add the "Content-Type" header to the headers.
