JsFiddle

Related to src/boot. I don't this I can implement a before the root Vue instance instantiation on JsFiddle

What did you get as the error?

Firebase: No Firebase App '[DEFAULT]' has been created - call Firebase App.initializeApp() (app/no-app)

Exception: TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them at Function.invokeGetter (:2:14)

What were you expecting?

Firebase to Initialize: I stepped thru the upgrade process via Quasar Team Upgrade Notes.md over an existing project. Prior to doing so, I C&P'd the project to a new directory and started a new vsCode instance. Before the app entrypoint, Firebase and FirebaseUI dependencies are utilized. The vsCode instances running ( side-by-side ); v0.17 runs as expected; v1.0.0-beta4 throws the above exception error: ...properties may not be accessed on strict mode functions... The only changes between the instances related is the renaming of the src/plugins dir to src/boot and the export function in the quasar.conf.js to reflect the directory change.

What steps did you take, to get the error?

Upgrade from v0.17 to ^v1.0 (See above section).

Attempts to remove the error:

Stripped down the boot file in question - firebase.js
Removed all other boot inits from the config file
Jumped on Discord and troubleshooted with @AllanGaunt(EN-GB)
Verified Firebase versions between the two instances
Upgraded Firebase from v5.8.3 to v5.8.4 in the Quasar v1 instance

Below is the boot file and a snippet from config.

module.exports = function (ctx) {
  return {
    // app boot plugins (/src/boot)
    boot: [
      // 'apexcharts',
      'firebase',
      // 'i18n',
      // 'svgicon',
      // 'vshowslide',
