i am new to service worker. I have been following Jake's lesson on Udacity but I am lost. I was trying to cache the avatars and i noticed whenever i npm run serve i get the error below and my locahost:8888 does not show images and my console pops alot of error message saying fetch request failed. Please what did i do wrong? my code below
