Remove a file from Ember project without Broccoli Plugin breaking [Firebase]

I'm having trouble removing a file from my Ember project without the Broccoli plugin breaking. I was playing around with Firebase hosting and firebase init basically added a ton of files to my project... Now there is an app/index.html file that won't let me load localhost as the index.html file just loads by default.

I can't remove the index.html file because if I do, I get this error:

file deleted index.html
The Broccoli Plugin: [ConfigReplace] failed with:

Now my Ember application just loads the index.html and I am stuck on what I should do to fix this problem...
