Uncaught TypeError: t is not a constructor

[IamDeshRaj]

After days of debugging as I'm new to angular. I found that ng2-datepicker throwing this error while running application in production mode using ng build --prod. In normal development mode using npm start it works perfectly fine.

Here is my package.json.

Hi,
I can confirm the same issue (Uncaught TypeError: e is not a constructor).
After removing the ng2-datepicker component from my project, it works fine.
However, I used Angular 7 and it only happens with AOT build
