hasCallExpression of undefined

I'm not sure what I'm missing here.

app.js 
const https = require("https");

let request = https.get("https://teamtreehouse.com/chalkers.json", response => {
  console.log(response.statusCode);
  });
request.on('error', error => console.error(error.message));

It's the function definition.

I'd guess the "undefined" has something to do with either this or arguments inside the checking code, neither of which get defined when you use the arrow form of function definition.

:point_right: Just use a conventional anonymous function definition to avoid this issue.

For whatever reason the above code worked...maybe some spacing or something was off. I have no clue why I was getting an error but all is well.

It looks like they fixed the checking routine. It previously would work with a conventional function but not an arrow function.
