What's the usage of "-ExpandProperties" parameter for Get-AzResource cmdlet?

[imeya]

I'm using Get-AzResource cmdlet with "-ExpandProperties" parameter, like below:

Get-AzResource -ODataQuery "$filter=resourcetype eq 'Microsoft.Web/sites'" -ExpandProperties`

But the result is same if I removed -ExpandProperties parameter, I wonder what's the usage of -ExpandProperties ? I read this doc, it says "When specified, expands the properties of the resource.". Not sure why the same result with/without this parameter.

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @armleads-azure

Involve Resource team to look into it. The example didn't describe it clearly.

I was facing the same issue earlier this morning. You can check out the example here (look for example 3):
https://docs.microsoft.com/ja-JP/powershell/module/azurerm.resources/get-azurermresource?view=azurermps-5.7.0#examples

Hope this solves your problem.

@arpitjain099 , thank you, I will take a look.

In my case -ExpandProperties throws an Error if I try to invoke Get-AzResource with a ResourceGroupName. MissingSubscriptionFilter : The query string does not contain a 'SubscriptionId' filter.
If I add -Name * it doesn't error but nothing is returned.
The main problem behind this is that it's not documented why querying a single resource returns a PSResource with a property Properties but querying multiple returns resources without it.
In conclusion, if you want to get the Properties property of all resources of a group, you need to get each resource separately, unless you specify the ResourceType (then -ExpandProperties works).
