I'm getting above error if I try to access different route in my node application. Please help

What do you mean 'diferent'? A route that you didn't configure? — pedromss

Where's your routes code? What route are you trying to access? — SlashmanX

The issue here is that the route in the about file is actually being resolved as /about/about. If you try open that URL it should work fine.

This is because in app.js, you say 'forward all requests that start with /about to about.js', so in about.js all routes already start with /about: app.use('/about', about);

To fix this, simply update the route in about.js to:

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