How to debug in the application.js with compressed javascript

Question

I got the following errors,

When I opened the Chrome javascript console,then look insight it.

application.js?body=1:1249

It is just a group of compressed js code

And I've open the in the development.rb

  # Expands the lines which load the assets
  config.assets.debug = true

I can not grep the any piece of the javascript source code in my Rails app.

So I don't know where does it come from ?

How can I fix the unknown error quickly in Rails ?

Thanks

Make sure sure you are running rails in development mode and

config.assets.compress = false

is set in development.rb

If you do not manage to get the uncompressed version you the another option:

Compressed files can be made "pretty" in Chrome if you click on the {} symbol. https://developer.chrome.com/devtools/docs/javascript-debugging#pretty-print
