Expected behavior

Injecting the AngularFirestore variable in the constructor of the AppComponent class should work without errors.

Actual behavior

The browser shows a 504 Gateway Time-out error and the Firebase Functions logs show the error above.

I also tried with the latest version of AngularFire2 5.0.0-rc.11 and it doesn't work either.

Interesting facts

I tried replacing the angularfire2 library with angularfire-lite and it worked, so it's definitely related to the combination of AngularFire2 and Firestore.
