can you please help me to get out of this ASAP Thanks, Looking Forward

your prod build using AOT?

[mateenQureshi]

yes exactly, should I remove Ahead Of Time Compilation while deploying production build ?

[ObaidUrRehman]

No, let me look into this.

For us, after Angular upgrade we had to import in app module and call forRoot()

[ObaidUrRehman]

@mateenQureshi did calling forRoot() solve your problem?

[mateenQureshi]

No, actually without calling forRoot() fixes my issue during building, but when I navigate to the app, the component which is using ng2-drag-drop breaks the app by throwing the above exception (ref: title of the issue)

Let me know if u need any further details Thank You

I had this same problem (I was using 2.0.2, then noticed my most recent update broke when I pushed and it deployed). I upgraded to 2.9.2 and called .forRoot.
