Cannot pass stylish-css challenge

[arku]

Code:

const express = require('express'),
      app = express(),
      path = require('path'),
      stylus = require('stylus'),
      port = Number(process.argv[2]);

let publicPath = path.join(__dirname, 'public');

app.use(stylus.middleware(publicPath));
app.use(express.static(publicPath));

try {
  app.listen(port);
} catch(err) {
  console.log(err.message);
}

Result of expressworks run(I have an alias setup)

$ ew run index.js 
p {
  color: #f00;
}

Result of expressworks verify

$ ew verify index.js 

Your submission results compared to the expected:

Why is the test looking for main.css in /usr/lib/node_modules/expressworks/exercises/stylish_css/public/?

What am I missing here?
