On version 0.2.0-alpha.3 When parsing this file there's an error on the parsings for mobile when transforming a line height value:

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

}

Most likely, this is happening on the transforms to dp, that are not checking if the values are numeric or not.
