Object cast bug when calling OData actions and functions that return a collection.

[nonodename]

Calling Get-MgGroupDelta with no parameters once connected results in a object cast error.

Steps to reproduce:

Install latest version (1.4.2) of the SDK.

PS C:\Users\db> get-installedmodule microsoft.graph

Version              Name                                Repository           Description
-------              ----                                ----------           -----------
1.4.2                Microsoft.Graph                     PSGallery            Microsoft Graph PowerShell module

Connect to graph

PS C:\Users\db> connect-graph -scopes "group.read.all","user.read.all"
Welcome To Microsoft Graph!

Run command

PS C:\Users\db> Get-MgGroupDelta
Get-MgGroupDelta_Delta1: Unable to cast object of type 'Microsoft.Graph.PowerShell.Runtime.Json.JsonObject' to type 'Microsoft.Graph.PowerShell.Runtime.Json.JsonArray'.

Thanks for opening this bug. This is an issue with how delta response is described in our OpenAPI documents and is being tracked by microsoftgraph/microsoft-graph-devx-api#307. I'll make a follow-up to see how far we are to having a fix.

@peombwa , this seems to affect Get-MgGroupMemberObject for instance which is a fairly common scenario. Is there an idea of the fix yet?

Hello @peombwa,

Same issue using cmdlet "Get-MgDirectoryObjectById"
