I get this error when trying to register the service worker:

Failed to register a ServiceWorker: A bad HTTP response code (404) was gwreceived when fetching the script.

I'm working with ionic and this is what I have in the app.js:

   if ('serviceWorker' in navigator) {

      navigator.serviceWorker.register('service-worker.js').then(function(registration) {

      console.log('ServiceWorker registration successful with scope: ', registration.scope);

    }).catch(function(err) {

      //registration failed :(

      console.log('ServiceWorker registration failed: ', err);

    });

  }else {

    console.log('No service-worker on this browser');

  }

On the directory I have the service-worker.js file right next to the app.js on the same folder.

Using latest chrome version on ubuntu desktop.
