Unable to pull results from MS Graph using powershell

Question

Hi Guys

We've pushed a PS script out via Intune to collect some data from end user devices. This has all worked perfectly, and if I log into MS Graph I can see the results of this at the URL:

https://graph.microsoft.com/beta/deviceManagement/deviceManagementScripts/c<scriptid>/deviceRunStates  

However, if I try and pull down the same results using PowerShell:

$result = Invoke-MSGraphRequest -HttpMethod GET -Url 'deviceManagement/deviceManagementScripts/<scriptid>/deviceRunStates?$expand=managedDevice' | Get-MSGraphAllPages  

I get the following error, which seems to indicate it can't find the referenced script object (I've set the environment to beta in PS):

Invoke-MSGraphRequest : 400 Bad Request      
{"error":{"code":"BadRequest","message":"Resource not found for the segment

Anyone got any idea where I'm going wrong?

TIA
