EDIT: Apparently related to this microsoftgraph/msgraph-sdk-dotnet-core#32

Is there any way to work around the issue e.g., with -HttpPipelineAppend?

@jpalo Thanks for informing us about this.
This is an issue with the code generator that we using to generate the cmdlets - it doesn't handle non JSON responses. We are currently work on a fix for this as part of work item #182.
