Set-MgUserLicense not allowing adding license "No license changes provided"

Question

I am able to remove licenses but trying to add the license returns the error "Set-MgUserLicense : No license changes provided. At least one license to add or remove must be specified."

Attempted several variations of SkuPartNumber lookup :

$EmsSku = Get-MgSubscribedSku -All | Where SkuPartNumber -eq 'EMSPREMIUM'  

Set-MgUserLicense -UserId "******@domain.com" -AddLicenses @{SkuId = $EmsSku.SkuId} -RemoveLicenses @()

or using the SkuID:

Set-MgUserLicense -UserId "******@domain.com" -addlicenses @{SkuId = 'b05e124f-c7cc-45a0-a6aa-8cf78c946968'} -RemoveLicenses @() 

Both return:
Set-MgUserLicense : No license changes provided. At least one license to add or remove must be specified.
