New-PowerBIWorkspace Command returns error

Hi

A resolution to problem described below would be extremely useful as this may explain why I am currently unable to utilise the CopyWorkspaceSampleScript to duplicate workspaces - as detailed in Kay Unroth's recent blog .

I am a Power BI Admin and can create workspaces in the Power BI Service on my tenant where App Workspaces are now the default Workspace mode.

I have installed the latest version of the MicrosoftPowerBIMgmt module (1.0.487)

However, on issuing the command New-PowerBIWorkspace -Name "New WS"

It returns an Internal Server Error as follows:

New-PowerBIWorkspace : Operation returned an invalid status code 'InternalServerError'
At line:1 char:1

• New-PowerBIWorkspace -Name "New WS"

•   + CategoryInfo          : WriteError: (Microsoft.Power...owerBIWorkspace:NewPowerBIWorkspace) [New-PowerBIWorkspace], HttpOperationException
    + FullyQualifiedErrorId : Operation returned an invalid status code 'InternalServerError',Microsoft.PowerBI.Commands.Workspaces.NewPowerBIWorkspace
  
  

On issuing the Powershell command Resolve-PowerBIError -Last, it returns:

RequestId : 4d767ec8-fe7c-41e1-8d18-0355045ceb5a
Response : Internal Server Error (500): {
"error":{
"code":"","message":"An error has occurred."
}
}

Many thanks.

Start with the New-PowerBIWorkspace entry point and the Resolve-PowerBIError output. Reproduce the POST to https://api.powerbi.com/v1.0/myorg/groups using the reported command and request details, then trace the workspace client path shown in the stack trace. Done means identifying the cause of the 500 response and confirming that workspace creation succeeds or documenting the required conditions.
