Rails 5 Heroku deploy error: ExecJS::ProgramError: SyntaxError: Unexpected token: name (autoRegisterNamespace)

Question

When trying to deploy a rails 5 app to heroku, I get the following error, when it reaches Running: rake assets:precompile:

remote:        ExecJS         


        

Answer 1

I had this issue and it was throwing Uglifier::Error: Unexpected token: name (subscription)

It ended up being an actual syntax error.

I accidentally had left the words "cancel subscription" in one of my JS files and it was causing it to throw that error
