The verified answer from the thread: If stencil bundle fails with 'Cannot read properties of undefined', check where your project lives. The reporter had theirs in Dropbox and the bundle succeeded after moving it to local storage. Cloud-synced folders can break the bundler. The Babel warnings in the output are nonfatal, ignore those.
