Copying the example also gives me this error, any clue?

mesutyigit commented 7 years ago

Did you solve. I've same issue

bastyen commented 7 years ago

Maybe you just copy paste some code (like the native elements example). So just remove the comment / ... more tabs here /. Should works after that.
