Is there an error with this challenge?

Tell us what’s happening:
When trying to submit this challenge I get:

// running tests

"Hello World"

should be in the console // tests completed

I tried doing npm start, but that didn’t work either:

app@sable-goldenrod-concavenator:~ 21:56 
$ npm start

> fcc-learn-node-with-express@0.1.0 start /app
> node server.js

Hello World
events.js:174
      throw er; // Unhandled 'error' event
      ^
