v2 SW error: Failed to execute 'importScripts' on 'WorkerGlobalScope'

[charlesfries]

Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'https://www.gstatic.com/firebasejs/9.0.2/firebase-app.js' failed to load.

I'm seeing this service worker error after the ECFA v2 update.

Steps to reproduce:

ember new my-app
cd my-app

ember install ember-simple-auth firebase ember-cloud-firestore-adapter ember-service-worker

ember generate adapter application
ember generate serializer application

// add config

ember s

I believe this may have to do with ember-service-worker wrapping the contents of sw.js in a self invoking function, in which case this issue is unrelated to this addon.

Actually this could be due to how Firebase modules are imported into the SW in v9: https://firebase.google.com/docs/cloud-messaging/js/receive#setting_notification_options_in_the_service_worker

I tried swapping the importScript calls for ESM imports, but I don't understand how ember-service-worker is going to be able to resolve anything unless we 1) bundle firebase-app and firebase-auth separately in the dist and import them into the SW, or 2 ) use fully qualified URLs.

Yeah, you're right. Thanks for catching this.

What we want to happen to quickly make this work is to importScript the firebase-app-compat.js and firebase-auth-compat.js. I will quickly make that change and release a fix to get it going but as with the other goals, long term is to slowly move away from compat SDK.
