Broken Absolute URI referenced by New-MGBetaDeviceManagementconfigurationPolicyAssignment

Question

We came across a broken reference of the absolute URI with the New-MgBetaDevicemanagementConfigurationPolicyAssignment PS cmdlet. The PS cmdlet is running into a HTTP 400 error and the same absolute URI is returning HTTP 400 on Graph as well

Absolute URI pointed by the PS command -   /deviceManagement/configurationPolicies/{deviceManagementConfigurationPolicy-id}/assignments -   Same URI returns HTTP 400 on Graph also

After capturing the network trace on the Intune portal we received the correct URI which returns HTTP 200 on Graph- Correct URI - https://graph.microsoft.com/beta/deviceManagement/configurationPolicies('<GUID>)/assign  

While we have already provided the workaround script to customer with Invoke-MgGraphRequest, I wanted to check if there is a work item already in progress to mitigate this buggy behavior. Customer wants to use the simplified PS cmdlets to pass them to the admins.

Can we get help with the correct Service/API owner for this.
