Graph-MgConnect error: Entry point was not found. Powershell 7.5.0

[alessandroere]

Describe the bug

I have a strange behavior using graph api. If i run a script through Visual Studio Code and Powershell extantion all works well but if i schedule the same script with task scheduler i get the entry point not found error.
I'm using powershell 7.5.0 for both Visual Studio Code and task scheduler execution. I have a lot of script run with task scheduler and all have the same issue.
As installed module i have only Graph module, MSAL.PS and SimplySql

This is the action configured on task scheduler:
Program/script: "C:\Program Files\PowerShell\7\pwsh.exe"
Add Arguments: -ExecutionPolicy Bypass -File "C:\script\test.ps1"

The execution policy is set to RemoteSign for both LocalMachine and CurrentUser

Expected behavior

If script execution works in visual studio code than it should also work with task scheduler

How to reproduce

schedule script with task scheduler

SDK Version

2.25.0

Hi @alessandroere maybe you could be having library conflicts between MSAL and graph PowerShell. Please share the output of this command. [system.AppDomain]::CurrentDomain.GetAssemblies() | Where-Object Location | Sort-Object -Property FullName | Select-Object -Property FullName, Location | Out-GridView

Hi @timayabi2020

This output is direct from Powershell via Visual Studio Code
outFileFromPowershellCli.txt

This output is direct from task scheduler execution

outFileFromPowershellFromTaskScheduler.txt

Thank you

[timayabi2020]

@alessandroere if you compare the two files, the output from the task scheduler is missing the Azure.Identity assembly hence the error.

Maybe you can try reinstalling the SDK with these parameters at the end -AllowClobber -Force or you can manually add the assembly in the script referenced by the task scheduler. i.e.

$IdentityLibPath = "C:\Program Files\PowerShell\Modules\Microsoft.Graph.Authentication\2.25.0\Dependencies"
Add-Type -AssemblyName (Join-Path $IdentityLibPath "Azure.Identity.dll")
