Search-MgDrive: JsonObject to JsonArray InvalidCastException

[Viajaz]

When handling the HTTP response (200 OK) an exception is thrown when using the Search-MgDrive Cmdlet. No issue with Graph Explorer.

CmdletException: InvalidCastException - Unable to cast object of type 'Microsoft.Graph.PowerShell.Runtime.Json.JsonObject' to type 'Microsoft.Graph.PowerShell.Runtime.Json.JsonArray'

Example usage of Cmdlet:

Search-MgDrive -DriveId $DriveId -Q "Sample Text"

Workaround example

$Response = Invoke-MgGraphRequest -Method GET -Uri "https://graph.microsoft.com/v1.0/drives/$($DriveId)/root/search(q='Sample Text')"
$Response.value | ForEach-Object { Write-Host "$($_.name) [$($_.id)] by $($_.createdBy.user.email) at $($_.webUrl)" }

Seems like Microsoft Graph has it's own undocumented endpoint of .../microsoft.graph.search instead of .../root/search.

Thanks for opening the issue. This is an issue with the OpenAPI document that the SDK is generated from and is being tracked here. Our recommendation is for customers to use Invoke-MgGraphRequest as shown above.
