Update-MgEntitlementManagementAssignment no http resource found

[jaoenrong]

Describe the bug

I am trying to update the schedule for an existing access package assignment with the -Schedule parameter, but it's throwing a now http resource was found error on the assignment ID, which was pulled directly with Get-MgEntitlementManagementAssignment cmdlet

Expected behavior

Either complete the update or return a syntax error on the -Schedule parameter

How to reproduce

$packagename='AccessPackage1'

$package=Get-MgEntitlementManagementAccessPackage -filter "displayname eq '$APname'" -all -ExpandProperty catalog,AssignmentPolicies

$filter="accesspackage/displayname eq '$APname'"

$assignments=@(Get-MgEntitlementManagementAssignment -ExpandProperty target,accesspackage,assignmentpolicy -filter $filter -All | ?{$_.state -ne 'expired'})

$schedule=@{ expiration=@{ EndDateTime=$null Type="noExpiration" } } Update-MgEntitlementManagementAssignment -AccessPackageAssignmentId $assignments[0].Id -Schedule $schedule

SDK Version

2.25.0, 2.28.0
