Looks like it could be your browser. Try and see if your app works in icognitomode. You could delete your cache and cookies. 

Might not be your code at all. See if it works for you.

@SkiDK ,

Looked at the other exceptions you listed and the one thing they had in common was none of them was the exact same error.  I did not try the other browsers or in private mode.  These are things that I tried:

- Remove component from screens = Error
- Delete component from component tab = Success

After this, future imports did not error. Probably another unsolved mystery.

v/r,

Hey @TiredOldCoder 

Ah I see. I guess that happens.
