SyntaxError: Unexpected token: punc (}) in rails:precompile

Question

I am trying to deploy to my staging server and all of a sudden I am getting the following error

V8::Error: SyntaxError: Unexpected token: punc (})
at js_error (<eval>:3623:12167)

Tasks: TOP => assets:precompile

I have run this rails code but everything looks to be ok I get no error for any of the javascript files.

JS_PATH = "app/assets/javascripts/**/*.js"; 
Dir[JS_PATH].each do |file_name|
  puts "\n#{file_name}"
  puts Uglifier.compile(File.read(file_name))
end

just crazy thoughts, I feel this regarding to your js file ya?, but my questions is whether you use vanilla js or not? — Kick Buttowski, Nov 14 '17 at 23:06

I got the same error and figured out why. This was because of using old Angular syntax format to find the record from json in angular which is deprecated and not supported with rails 4 and later version.

Syntax not supported:

Json_data.find(item => item.field_name == 'abc').
