After upgrading to Chrome 64, I realized that this error appears when I load my page on a new tab.

I can't identify where it is on the service worker. Here is my code to run the fetch:

self.addEventListener('fetch', function(event) {

   if (event.request.url.startsWith(self.location.origin)) {

       event.respondWith(

           caches.match(event.request).then(function(response) {

              return response || fetch(event.request).then(function(fetch_resp){

                  return fetch_resp;

              });

           })

       );

   }

});

Could anyone here, who has more knowledge about service worker, help me to solve this error?
