Set-MgUserLicense optimizes out necessary empty parameters

[dt-flo]

Describe the bug

I hope the titel is alright, please tell me if I should change it if it is unclear.
When running the command Set-MgUserLicense -UserId "great@account.com" -RemoveLicenses @("b70a4eeb-32f6-4c99-af47-3c822a4bbc59") -AddLicenses @() as described for example in Example 6 in the MS docs, the Graph SDK detects that -AddLicenses @() is essentially empty and omits it from the HTTP request. However, the Microsoft Graph API requires that AddLicenses is present even though it is empty. The same behavior can be reproduced with RemoveLicenses

Example:
Set-MgUserLicense -UserId "great@account.com" -RemoveLicenses @() -AddLicenses @() -Debug results in

an empty body and therefor in the error

. The command Set-MgGroupLicense has the exact same issue. I am using Graph SDK 2.26.1.

Expected behavior

The SDK should neither omit AddLicenses, nor RemoveLicenses

Hi @dt-flo apologies for the inconvenience. This issue was already reported hereand the fix for it will be available by end of next week. I'll therefore close this as a duplicate

Please provide the fix ASAP as this is a essential command for us to assign licenses. (2.26.1 have so many bugs as reported)
