Get-MgEntitlementManagementAssignmentPolicy returns "An item with the same key has already been added"

[Xiaojing123456]

Describe the bug

When I run Get-MgEntitlementManagementAssignmentPolicy in China Azure Cloud, it returns "An item with the same key has already been added". However, I can get normal return when trying other commands, like Get-MgEntitlementManagementAccessPackage. Moreover, it's working through REST API rather than Microsoft Graph Powershell.

Expected behavior

Please help check what's going wrong with command Get-MgEntitlementManagementAssignmentPolicy & New-MgEntitlementManagementAssignmentPolicy. Is it a bug? The same command works fine in Global Azure.
