PowerShell ConvertFrom-Json Does not Create All Properties of API Result

TravisKale — Wed, 03 Feb 2021 13:51:24 GMT

I am issuing the following via PowerShell

$apiResult = Invoke-PowerBIRestMethod -Url 'https://api.powerbi.com/v1.0/myorg/admin/groups?$expand=dashboards,users,reports,datasets,dataflows,workbooks&$top=5000' -Method Get | ConvertFrom-Json

The call works and everything is returned, however, on the Group object there is only a boolean "IsOnDedicatedCapcity" field, and not a CapacityId.

If I exclude the | ConvertFrom-Json, and look at the Raw JSON, the property is there. I'm guessing since the first object returned does not have a CapacityId, when PowerShell tries to create an ojbect to store the result that the CapcityId property is excluded.

To test this theory I changed the API call to use a filter to only return groups on a capacity via...

'https://api.powerbi.com/v1.0/myorg/admin/groups?$filter=isOnDedicatedCapacity eq true & $expand=dashboards,users,reports,datasets,dataflows,workbooks&$top=10'

Now, when I issue the ConvertFrom-Json, the CapacityId property is present on the object PowerShell creates for me.

This is probably more of a PowerShell question at this point but is there a way to force the ConvertFrom-Json method to include all properties in the object array even if the first element property is not present?

wonder what happens when you don't expand the related entities?

Calls which did not expand the related entities had the same result. I did further testing and modified the original post with updated info. Is more a powershell issue then a Power BI API issue. I guess this is why the cmdlets exist, I am going to turn back to the PS cmdlets as the issue I was having with them is easier to workaround than this issue. Thanks for taking a look @lbendlin
