Graph API bug "assignLicenses"

[OtterKring]

Describe the bug

Assigning and removing licenses from users has stopped working this monday, regardless if I use Microsoft.Graph module 2.25, 2.26.1 or Invoke-MgGraphRequest.

Error sources I can rule out so far:

• missing permissions. My application permissions have not changed
• typos. I am using the same function for years now and the problem started this week, manual or with the function.

This is the code I use for removing licenses:

... | %{get-mguser -userid $_ -Property id,assignedlicenses | %{Set-MgUserLicense -UserId $_.id -RemoveLicenses $_.assignedlicenses.skuid -AddLicenses @() }}

I get the following error message:

Set-MgUserLicense_AssignExpanded: One or more parameters of the operation 'assignLicense' are missing from the request payload. The missing parameters are: addLicenses.

When adding a license like this:

... | %{get-mguser -userid $_ | %{Set-MgUserLicense -userid $_.id -AddLicenses @(@{skuid='f30db892-07e9-47e9-837c-80727f46fd3d'}) -RemoveLicenses @()}}

I get this(same) error message:

Set-MgUserLicense_AssignExpanded: One or more parameters of the operation 'assignLicense' are missing from the request payload. The missing parameters are: removeLicenses.

using Set-MgBetaUserLicense (Module 2.26.1)

Same issue.

Expected behavior

Well, licenses should be added or removed. 🤷‍♂️

How to reproduce

See "Describe the bug"

SDK Version

2.25, 2.26.1

Latest version known to work for scenario above?

I don't think it is related to the modules, but to the API itself

Known Workarounds

Use admin.microsoft.com. Tedious if you have a lot of users to process.

Hi @OtterKring apologies for the inconvenience. This issue was already reported here #3201 and the fix for it will be available in the next release. I'll therefore close this one as a duplicate of that one.
