Datasets GetTablesInGroup API call does not return columns

[RemcoTMDi]

Hello,

I am trying to get the table schema of existing Push Datasets by using the GetTablesInGroup API call.

This returns the following response (redacted the group id):

{
  "@odata.context":"http://wabi-north-europe-redirect.analysis.windows.net/v1.0/myorg/groups/{group-id}/$metadata#tables",
  "value":[
    {
      "name":"RealTimeData"
    }
  ]
}

However I expected the response to be like this:

{
  "@odata.context":"http://wabi-north-europe-redirect.analysis.windows.net/v1.0/myorg/groups/{group-id}/$metadata#tables",
  "value":[
    {
      "name":"Server Status"
      "columns": [
        {"serverName": "text"},
        {"serverStatus": "number"}
      ]
    }
  ]
}

Which is more in line what is modeled on the Power BI Workspace webpage, as well as what is specified in the documentation of the GetTablesInGroup call.

So what am I doing wrong here?
