title: Progressive Web App: The FetchEvent for "<URL>" resulted in a network error response: the promise was rejected
body: <p>I am seeing the following errors in the console of my PWA:</p>
  <ol>
  <li>The FetchEvent for &quot;https://static.cloudflareinsights.com/beacon.min.js&quot; resulted in a network error response: the promise was rejected.</li>
  <li>The FetchEvent for &quot;https://www.google-analytics.com/analytics.js&quot; resulted in a network error response: the promise was rejected.</li>
  </ol>
  <p>It seems that external scripts have problems being fetched by workbox? The website is a next.js app and i am using next-pwa to turn it into a PWA. Here is the pwa-config for next-pwa: <a href="https://i.stack.imgur.com/HRLu7.png" rel="nofollow noreferrer">next-pwa config</a></p>
  <p>Does anyone know how to fix this?</p>
