PowerShell authentication with service Principal failing

[BoNDoK00]

$client_id = <ClientID>
$tenant_id =  <SecretID>
$secret =  <Secret>


$SecurePassword = ConvertTo-SecureString $secret -Force -AsPlainText
$servicePrincipal = New-Object -TypeName PSCredential -ArgumentList $client_id, $SecurePassword

Connect-PowerBIServiceAccount -ServicePrincipal -Credential $servicePrincipal -Environment Public -Tenant $tenant_id

returns 

Environment : Public
TenantId :
ClientId : <ClientID>
Password : ********

As you can see tenantid is returned as empty.  When I try to call APIs I get this error message:

Invoke-PowerBIRestMethod : One or more errors occurred.
At line:1 char:1

 What am I doing wrong?

Hi @BoNDoK00 

What kind of API are you using and can you provide the API you are using for testing ?
