Test-MgServicePrincipalSynchronizationJobCredential do not return bool value

[MasterKuat]

Describe the bug

I'm testing new credential validatity for ServicePrincipal sync job (Enterprise app / SCIM job).
Per documentation this cmdlet must return boolean.

But if credential is correct, the cmdlet return nothing.

API return a status 204, No Content as expected.
Surely the root cause.

If credential is wrong, cmdlet report an error.

Expected behavior

Return $True or $False without Error

How to reproduce

$params = @{
credentials = @(
@{
"key" = "BaseAddress"
"value" = "mytenantURL"
},
@{
"key" = "SecretToken"
"value" = "MySecretToken"
}
)
}

Test-MgServicePrincipalSynchronizationJobCredential -ServicePrincipalId $EnterpriseApp.Id -SynchronizationJobId $Syncjob.Id -BodyParameter $params

Hi @MasterKuat thank you for raising this issue. This is indeed an issue with the PowerShell reference documentation. Kindly allow us to investigate why the output documented in the reference document does not coincide with what has been documented in the API reference document.

As for the request in regard to API response having a Boolean value for both success and fail scenarios, please raise an issue here so that the service owner can respond to it.
