When I run my angular application with ng serve it works. However when I am deploying (either Jboss or Tomcat Servers) same angular application it gives following at console:

Uncaught ReferenceError: Cannot access 'GA' before initialization

    at Module.zUnb (main-es2015.faddfe3f773581d6c95a.js:1)

I have used ng build --prod ---base-href=myapp to build my module.

What could've possibly gone wrong?

Optional: I have already tried "emitDecoratorMetadata": false based on a solution on another thread. But still issue persists.

For this problem, I have figured out this was due to some compilation from the typescript to the javascript issue. I have managed to fix this by a workaround just by initializing GA (please note this GA is dynamically changing with each build compilation) at javascript manually after ng build. And it fixed.

A similar issue has been discussed at Gitlab forum.

further explaining my solution:

    var GA; // manually declared initializing here.
    return e.ngInjectableDef=ue({factory:function(){return new GA},token:GA,providedIn:"root"})
