Sdkbox-firebase integration in creator

i imported firebase plugin from the gui of creator and there are a couple of errors in the firebase.d.ts generated file. that is not allowing me to init the firebase analytics plugin from my ts code in the project.
i am also including a screenshot of the AppDelegate.cpp file to make sure things are fine from that end.

AppDelegate.cpp:

firebase.d.ts(line 7):

my project ts code:

i am using cocos creator ver-2.4.3 and sdkbox gui ver-1.4.1, and i think there is some problem with the file firebase.d.ts(line 7).

please guide.
thanks!

Edit: just to try something i changed line 7 of firebase.d.ts to :

declare module sdkbox.firebase {

this way in my code ,

sdkbox.firebase.Analytics.init();

was not underlined in red. however my app crashed upon launching.
