Please read my reply again.  Use -Method  (note the dash)

    Thank you, I changed the code but getting this new error now:

    Invoke-PowerBIRestMethod -Url $Url -Headers $authHeader -Body $jsonPostBody -Method POST -Verbose

      Looks like 

       

      Get-PowerBIAccessToken -AsString

       returns more than you need. Investigate that and then only use the auth part.

       

      most likely

      $authHeader = @{
      'Content-Type'='application/json'
      'Authorization'=$token.Values[0]
      }

        Hmm, maybe the issue is elsewhere. Both

         

        Connect-PowerBIServiceAccount
$headers = Get-PowerBIAccessToken -AsString
$authHeader = @{
'Content-Type'='application/json'
'Authorization'=$headers
}
Invoke-RestMethod -Headers $authHeader -Uri 'https://api.powerbi.com/v1.0/myorg/groups'

         

        and 

         

        Connect-PowerBIServiceAccount
$headers = Get-PowerBIAccessToken 
Invoke-RestMethod -Headers $headers -Uri 'https://api.powerbi.com/v1.0/myorg/groups'

         

        work for me.

         

        Maybe Invoke-PowerBIRestMethod is the culprit.  Use Invoke-RestMethod instead.
