Uglifier::Error: Unexpected token: name (package)

[ghost]

I have a package parameter/argument in a JavaScript function. During precompilation process in the deployment, it raises an error Uglifier::Error: Unexpected token: name (package) and the deployment halts. Renaming package to another name solves the issue.

staging.rb / production.rb

config.assets.js_compressor = Uglifier.new(harmony: true)
