Api - Page can't be found

Question

I'm requesting some data from an API - in particular https://api.tvmaze.com/singlesearch/shows?q=Friends&embed=episodes usually, when I get an invalid request with APIs I get it in JSON format. So I can easily send that data back (to discord). But with this API if you replace friends with a random string it returns a page saying This api.tvmaze.com page can't be found. How can I send this data back to the user?

I'm using NodeJS and the node-fetch module to get the request.

fetch('https://api.tvmaze.com/singlesearch/shows?q=' + msg + '&embed=episodes') //msg is the users input
  .then(function(res) {
    return res.json();
  }).then(function(json) {
    console.log(json.network.name) // if input is friends this returns NBC
  });

Answer 1

So I am not 100% familiar with node-fetch but I think you can check the status of the res in your .then() function.

fetch('https://api.tvmaze.com/singlesearch/shows?q=' + msg + '&embed=episodes') //msg is the users input
  .then(function(res) {
    if(res.status === 404) {
        //HANDLE THE 404 Page Not Found
    } else {
        return res.json();
    }
  }).then(function(json) {
    console.log(json.network.name) // if input is friends this returns NBC
  });
