TfsCmdlets Get-TFSGroup returns Error getting descriptor for project '' API resource location '' is not registered on

[rhino2334]

Are all of the functions of TfsCmdlets compatible with azure devops server 2020?
I'm able to use Get-TfsTeamProject to get the list of all projects within a project collection, but when i try to loop through and then use a project name with Get-TfsGroup as shown in the following line, "Get-TfsGroup -Collection $FISCollection -Project $proj.Name -Scope Project", I get this error:
Get-TfsGroup: Error getting descriptor for project 'ProjectName' (API resource location GUID is not registered on https://myAzureDevopsUrl/CollectionName.. )

You're right - Azure DevOps Server 2020 does not have the API required for the Get-TfsGroup cmdlet.

As an workaround, you can try the following to get a single group:

$proj = 'YOUR_TEAM_PROJECT_NAME_HERE'
$group = 'YOUR_GROUP_NAME_HERE'
$g = Get-TfsIdentity "[$proj]\$group"
$members = $g.MemberIds | ForEach-Object { Get-TfsIdentity $_ }

However, if you're trying to enumerate the groups of said project, then there's another workaround. The basic idea here is to via the members of the Project Valid Users group. It contains all valid users (and groups) in the given team project. From there, you can get the groups you're looking for:

$proj = 'YOUR_TEAM_PROJECT_NAME_HERE'
$pvu = Get-TfsIdentity "[$proj]\Project Valid Users"
$allIdentities = $pvu.MemberIds | ForEach-Object { Get-TfsIdentity $_ }
$groups = $allIdentities | Where-Object IsContainer -eq $true

HTH!

I'm adding a fix to it to the backlog, so that Azure DevOps Server users can user Get-TfsGroup in the future.

Thanks for the quick response Igor! I will try your suggested workarounds.

The workaround worked perfectly. Thanks again.
