New-MgApplicationOwnerByRef throws: A 'StartObject' node was expected

[erwinkramer]

Using the latest stable release.

Can't seem to get New-MgApplicationOwnerByRef working, I've tried a few solutions but this what i think should be working:

$body = @{
           "UserId" = $user.Id
       }
      
New-MgApplicationOwnerByRef -ApplicationId $adApp.Id -BodyParameter $body

Which returns the following error:

New-MgApplicationOwnerByRef : An unexpected 'EndOfInput' node was found when reading from the JSON reader. A 'StartObject' node was expected.

You'll need to explicitly provide the @odata.id to the body parameter as shown in the docs. This can be done in PowerShell:

$Body = @{ "@odata.id" = "htps://graph.microsoft.com/v1.0/directoryObjects/$UserId" }
New-MgApplicationOwnerByRef -ApplicationId $AppId -BodyParameter $Body

We may also need to provide a simplified parameter set of this command that just accepts a directoryObjectId and builds the @odata.Id behind the scene. Something like this:

New-MgApplicationOwner -DirectoryObjectId $UserId

All $ref (*ByRef) commands now support -ODataId. In v2, -ODataId is required for POST, PATCH, and PUT. See https://learn.microsoft.com/en-us/powershell/module/microsoft.graph.applications/new-mgapplicationownerbyref?view=graph-powershell-1.0,
