Vue.js codes are not working in Production

I'm working on a client webapp which is on Laravel 5.6 with Vue.js (2.5.7). I'm new to Vue.js. Today, I updated few of my Vue.js codes and pushed to production. It is working on local but is not working on Production, although I can clearly see the codes there.

Can an Vue expert please suggest what could be the reason?

Thanks in advance,
