Cannot import Firebase project

Question

I have an existing Firebase project that I am trying to import into the new Firebase 3.0 version that was just released at Google I/O 2016. Every time I try to import it, I keep getting this error with no helpful message on how to fix it or what the actual problem is.

Answer 1

It Sometimes related to your extensions that you have added them before for example I had Enable Cross Origin * Extension and Firebase did nothing at all.
