Express is not handling errors for function

Question

I'm using a function for multiple times by calling from different routes. It's running but express/node.js not handling errors in the function.

Here's the example.

# routes.js
var app = express()
var { test } = require('../functions/test.js')(app)

router.get('/test', (req, res) => {
  console.log(test())
})

# test.js
function test() {
  return 'Hey'
}

module.exports = function(app){
  return { test }
}

If I call a function in test() which is not exists, It's not throwing errors and returns nothing inside console.log(test())

# test.js
function test() {
  heyHeyheyHey()
  return 'Hey'
}

module.exports = function(app){
  return { test }
}

Do I have to define this module in somewhere or something?

I ran a quick demo and the error has been thrown. I'm sure you've figured it out but here is my snippet.
