How make build without javascript code minification?

When an error occurs in the code, the first line is always specified.
This makes debugging very difficult.
Error example:

Uncaught SyntaxError: Unexpected reserved word Application.js:1

Can you please share with us a sample app that reproduces the error at developer@lge.com?

You can use --no-minify option when you package an app.
Please refer to here.
