Chrome works fine but Firefox JS Error

I had try remove fallbackImage from filesToCache so it becomes const filesToCache = [startPage, offlinePage]; but it still not working.

Hello @infinitymusics

Thanks for the kind words.

Even though I have seen this error before I haven’t had a chance to figure it out yet. Jose and I are looking into it.

Interesting thing is that I cannot see the error on your website anymore, but I have seen this in the past. Are you seeing on the homepage? or a different page?

I will do some tests and get back to you with a suggestion soon.

It can be see in both homepage and post page. Thank you and hope hearing for the solutions soon.

I changed the code to become like this so it will works.

// Install
self.addEventListener(‘install’, function(e) {
console.log(‘SuperPWA service worker installation’);
e.waitUntil(
caches.open(cacheName).then(function(cache) {
console.log(‘SuperPWA service worker caching dependencies’);
//return cache.addAll(filesToCache);

/*
Solution 1
return Promise.all(
filesToCache.map(function (url) {
return cache.add(url).catch(function (reason) {
return console.log(url + “failed: ” + String(reason));
});
})
);*/

// Solution 2 without debug
return Promise.all(
filesToCache.map(function(url){ cache.add(url) })
);
})
);
});

SuperPWA 1.9 should take care of this.
