@azchohfi anything missing here that is causing this error?

[azchohfi]

0.5 libraries are not compatible with 0.8, especially with the release candidate that has some nasty bugs. I have a local branch with 0.8 RC changes, but it is not in a state we want to ship. We'll ship a new version of the toolkit only when there is a 0.8-GA (not RC). That should not take long.

Awesome, thanks for the quick answer!
