Object reference not set to an instance of an object on New-AzureADMSInvitation about azure-activedirectory-powershell HOT 3 OPEN

The cause of this error seems to be, that some Tokens (got mine with the MSAL.PS module) can't be processed properly by the module and result in this error. If I invoke the request myself it works fine.
This is the solution in case you have the same problem:

Invoke-RestMethod -Uri https://graph.microsoft.com/v1.0/invitations -Method POST -UseBasicParsing -Body "{`"invitedUserEmailAddress`":`"$email`",`"inviteRedirectUrl`":`"$redirectUrl`", `"invitedUserDisplayName`":`"$lastname, $firstname`"}" -Headers @{"Authorization"="Bearer $($token.Accesstoken)"}

+1 hitting this running under an SPN from an ADO pipeline. Thanks for the hint on the token.

Edit:
Looks like this was a bad implementation on my end. I needed to pass both the AaDAccess token and the MSAccessToken to Connect-AzureAD. There are a number of bad implementations that come up in web searches.
