REST API Admin - Groups AddUserAsAdmin:"Parameter PrincipalType or Identifier is missing or invalid"

[DavidS524]

Hi everyone,

I am trying to use the REST API to add a mail-enabled security group as an admin on a workspace. I get the following error when using this format:

{
groupUserAccessRight: "Admin",
identifier: "[objectID of the group]",
principalType: "Group"
}

Result: 

{
  "error": {
    "code": "InvalidRequest",
    "message": "Parameter PrincipalType or Identifier is missing or invalid"
  }
}

I've tried every variation I can think of, including using the email address and displayname of the group as the identifier, or as separate parameters. In contrast, adding one of my colleagues as a user with their email address works just fine:

{
groupUserAccessRight: "Admin",
identifier: "[email address]",
principalType: "User"
}

For more context, I have also used the "Datasets - Post Dataset User In Group" API call to successfully grant a mail-enabled security group access on a dataset using the objectID:

{
datasetUserAccessRight: "ReadExplore",
identifier: "[objectID of the group]",
principalType: "Group"
}

This results in a successful Response Code 200 and the group is granted permissions.

After Googling around, I saw some posts from a few years ago with similar errors where the suggestion was to make sure the workspace was the newer version. The workspace I am trying to add this to was just created this week so that is not the issue. 

Any other ideas?

Thank you!

Being Admin of the WS doesn't mean you are the Admin of the tenant. APIs with ****AsAdmin are for Power BI administrator of the tenant only. Must use this

I am a TENANT admin and I am trying to add a group to all workspaces. Specifically, I want to use this:  https://learn.microsoft.com/en-us/rest/api/power-bi/admin/groups-add-user-as-admin

I have used the API to add my user id but I am not able to use on a group. It seems the API doesn't work when you use a group. 

Here is my code

$jsonRequestBody=@{
  identifier            = "xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx"
  principalType         = "Group"
  groupUserAccessRight  = "Admin"
}|ConvertTo-Json

Connect-PowerBIServiceAccount

$workspaceId= "xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx"
Write-Output "https://api.powerbi.com/v1.0/myorg/admin/groups/{$workspaceId}/users"
#Invoke-PowerBIRestMethod -Url "https://api.powerbi.com/v1.0/myorg/groups/{$workspaceId}/users" -Method Post -Headers $authHeader  -Body $jsonRequestBody -Verbose
$request=Invoke-PowerBIRestMethod -Url " https://api.powerbi.com/v1.0/myorg/admin/groups/$workspaceId/users" -Method Post -Verbose -Body $jsonRequestBody

Invoke-PowerBIRestMethod : One or more errors occurred.

There response is

  "code": "InvalidRequest",
  "message": "Parameter PrincipalType or Identifier is missing or invalid"

The same code works well when I modifiy the body to
$jsonRequestBody=@{
  emailAddress            = "myuser@myorganisation.com"
  principalType         = "User"
  groupUserAccessRight  = "Admin"
}|ConvertTo-Json

The Identifier, where do you get it from? it can't be the name of the security group

[tumuju]

I got the identifier Azure AD. The identifier is object id of group.

Membership type: assigned

Source: Windows AD Server

Object ID: <This is what I am using as the identifier>

The object is a group with members of type user. 

Thanks

I am experiencing the same issue. Trying to add a security group to workspace as Admin results in the error: 'message': 'Parameter PrincipalType or Identifier is missing or invalid'.

If replace the security group with an ordinary user, it works well.
