If applicable, add screenshots to help explain your problem.

Additional context
Workaround is to add some fake property to folder facet

Import-Module Microsoft.Graph.Files

$params = @{
	name = "New Folder"
	folder = @{
        x = 'x'
    }
	"@microsoft.graph.conflictBehavior" = "rename"
}

New-MgDriveItemChild -DriveId $driveId -DriveItemId $driveItemId -BodyParameter $params

@MartinM85 thanks for identifying and logging this issue. Indeed, there is an issue with how the SDK packages the request body especially when a nested object doesn't have a key-value pair. Thank you for also providing a workaround 👍

when I do above I get:

New-MgDriveItemChild_Create: The item must have a name.
