@leekelleher - Hi Lee, I had the same issue earlier today so I downloaded your source code to see if I could help by submitting a PR, however after setting up the test solution locally, it works. So rather than me spend more time digging into this, I thought I'd check with you to see if you have already fixed this issue and if it would be in your next alpha release?

If not, I can confirm that I am experiencing the same issue as above with your latest alpha release.
