Hi @quentinmarois from the debug information this seems like a service issue. You can also confirm that this issue is not only specific to the Microsoft PowerShell SDK by making use of this tool https://developer.microsoft.com/en-us/graph/graph-explorer. by picking the request uri from the debug information and running it on the tool. For API related issues/questions we are not best placed to give an answer. Kindly raise an issue here https://developer.microsoft.com/en-us/graph/support so that the API owner can respond to it.

So I did a bit more research on the issue, but I'm getting more confused.
The API actually seems to behave as expected: In this page and this page of the documentation, it is mentioned that to delete an access package assignment, we need to create a new request with the corresponding type of the initial assignment request.

So for example, if the original assignment request was of requestType AdminAdd, we create a new request of type AdminRemove

So, it would make sense that the API return an error, because the DELETE method doesn't exist (although the error status code is a bit misleading as the endpoint does exist, but not the method. A 405 error would make more sense).

The thing that I'm having difficulty understanding now is that, if this is the intended process, wouldn't this mean that the Remove-MgBetaEntitlementManagementAccessPackageAssignement command should not exist in the first place ?

Thanks for the info @quentinmarois.

I got removal working with New-MgEntitlementManagementAssignmentRequest.

What's also not.. legit.. with Graph is that I successfully could create the remove request without any write permissions in the scope when I authenticated. I authenticated with:

do {$Disconnected = [bool](-not$(Try{$null = Disconnect-MgGraph 2>$null; $?}Catch{$false}))} until ($Disconnected)
Connect-MgGraph -UseDeviceCode -Scopes ('AuditLog.Read.All','EntitlementManagement.Read.All','User.Read.All') -NoWelcome -ContextScope 'Process'

And the delete request went through, no questions asked.

• Edit: This is by design apperently: Should previous scopes show in new session started with Connect-MgGraph? #587

After that it takes some minutes before the request is "delivered", as in assignment is actually deleted. Then the assignment status is "expired".
