Using InjectManifest in PWA

tamirvs

Hi,
I’m trying to create a PWA app using InjectManifest.
My service-worker.js has this code (as seen in many examples):

precacheAndRoute(self.__WB_MANIFEST);

registerRoute(
  new NavigationRoute(createHandlerBoundToURL('/index.html'))
);

But I’m getting an error:

Uncaught non-precached-url: createHandlerBoundToURL(’/index.html’) was called, but that URL is not precached. Please pass in a URL that is precached instead.

How can I get index.html to be precached?
