No method match route template when executing Remove-MgBetaDeviceManagementScriptGroupAssignment

Issue Summary
When executing the Remove-MgBetaDeviceManagementScriptGroupAssignment a status 400 (BadRequest) is received. I receive the same response in Graph Explorer.

Referenced Graph documentation: https://learn.microsoft.com/en-us/graph/api/intune-devices-devicemanagementscriptgroupassignment-delete?view=graph-rest-beta

To Reproduce

1. Execute the following ($IntuneScript and $IntuneScriptAssignments return results in my tenant):

$ScriptName = "Escrow Bitlocker Recovery Keys"
$IntuneScript = Get-MgBetaDeviceManagementScript -Filter "displayName eq '$ScriptName'"
$URI = "https://graph.microsoft.com/beta/deviceManagement/deviceManagementScripts/$($IntuneScript.Id)/groupAssignments"
$IntuneScriptAssignments = Invoke-MgGraphRequest -Uri $URI -Method GET
$Assignment.id = $IntuneScriptAssignments.value.targetGroupId[0]
Remove-MgBetaDeviceManagementScriptGroupAssignment -DeviceManagementScriptId $IntuneScript.Id -DeviceManagementScriptGroupAssignmentId $Assignment.id

2. Execute a DELETE against https://graph.microsoft.com/beta/deviceManagement/deviceManagementScripts/{deviceManagementScriptId}/groupAssignments/{deviceManagementScriptGroupAssignmentId} in Graph Explorer

Debug Output
In PowerShell:

DEBUG: [CmdletEndProcessing]: - Remove-MgBetaDeviceManagementScriptGroupAssignment end processing.
> $ScriptName = "Escrow Bitlocker Recovery Keys"
$IntuneScript = Get-MgBetaDeviceManagementScript -Filter "displayName eq '$ScriptName'"
# Management Scripts Assignments URI
$URI = "https://graph.microsoft.com/beta/deviceManagement/deviceManagementScripts/$($IntuneScript.Id)/groupAssignments"
$IntuneScriptAssignments = Invoke-MgGraphRequest -Uri $URI -Method GET
$intunescriptassignments.value.targetgroupid[0]| foreach {
    Remove-MgBetaDeviceManagementScriptGroupAssignment -DeviceManagementScriptId $IntuneScript.Id -DeviceManagementScriptGroupAssignmentId $_ -Debug

Start with the failing Remove-MgBetaDeviceManagementScriptGroupAssignment command and compare its DELETE request with the referenced Microsoft Graph endpoint and the Graph Explorer result. Verify whether the route accepts the supplied device management script and group assignment IDs; done means the documented DELETE request returns success rather than "No method match route template."
