var todos = require('../../mock/todos.json');

var router = express.Router();

router.get('/todos', function(req, res) {

By looking at your repository it doesn't appear to have the "mock" folder at the root of your project. Can you verify that you have a "mock" folder at the root of your project with todos.json in that folder?

This is late, but what Ken said. If you pulled the git repository and didn't create your mock like in the video, then your mock folder is in your public. So your todos would include the path to the public folder, then mock.

var todos = require('../../public/mock/todos.json');

Hey Ben,

*See Justin's comment above.

If you missed it, change: 

var todos = require('../../mock/todos.json');

to (just missed the public off the path):

var todos = require('../../public/mock/todos.json');

you cannot make a get request for files that are not being served, the express server is set up to serve from "public" so you have to put the mock folder in the public folder and change the path in index.js accordingly, I think this was an uncaught glitch in the course. it does not work if mock is in the root
