APIs Explorer: App EngineGo to Lab
This was good, but for some reason when I deployed the app for the first time I got an failure error "Build error details: Build error details not available.", but repeating the deploy command worked fine.
Great lab ! But I thought it was kind of negative to change from "Hello World" to "Goodbye world!" so I just added "AGAIN" in the middle (more positive IMHO) ;)
