Pretty Print is not working in chrome console for production app.js files

I am using production build and getting dome error :

Error : Uncaught SyntaxError: Identifier 'b' has already been declared

My dev build is working fine, in production build I am not able to get the problem as my pritty print is not working.

Screenshots.

It is working for other builds but not for this specific apps.(note : This app consist two more apps, though taht not should be an issue.)

I have gone through other answers but none of them are use full for me. Any help will great.
