@blackadi thanks for identifying and reporting this issue. The cmdlet corresponds to this /users/{user-id}/authentication/methods/$count Microsoft Graph Api path which unfortunately I'm not able to trace its reference documentation here. It seems the $count path parameter is not supported; however, I've opened an issue here microsoftgraph/msgraph-metadata#648 for tracking purposes.

[blackadi]

@timayabi2020 do you have a feedback if this is supported or not.

[matt-gribben]

@blackadi I've also run into this issue, it seems that $count used to exist but no longer does (it was at least available when Microsoft.Graph.Beta C# package 5.56.0 was published as I used it then). This endpoint seems to still exist in the latest C# package as well but doesn't work...
