"updateCurrentUser failed" error on screen, after using 4.7.1 via ES module import

Describe your environment

• Operating System version: macOS
• Browser version: Chrome 85
• Firebase UI version: 4.7.1
• Firebase SDK version: 8.0.0

Describe the problem

The ability to import as ES module in 4.7.1 is something I have been looking forward to. Bringing it in in my application, I found two problems. This issue describes the more crucial one, which I don’t understand and can not find a way around.

After changing my code to use import instead of loading via the globals, and signing in with Google account, I see this:

I have no idea, where it comes from.

Steps to reproduce:

1. Clone https://github.com/akauppi/GroundLevel-es-firebase-app
2. Set up a Firebase project to work against (please read the README, until you can npm run dev:online).
3. npm run dev:online

Open the browser at http://localhost:3001 and try Google sign-in.

Expected: one should get to the app Actual: the above error is shown

Relevant Code:

Unfortunately, I don’t have a minimum reproducing project available. Merely scouting, if other are also seeing this.

Same, local not working. Production seems fine. edit: seems to be the buildDir location being within firebase functions folder

"@nuxtjs/firebase": "^7.5.0",
    "firebase": "^8.3.1",
    "firebaseui": "^4.8.0",

    // nuxt.config.js
     target: "static",

    services: {
      auth: {
        persistence: "local",
        initialize: {
          onAuthStateChangedAction: "onAuthStateChanged"
        },
        ssr: false // true doesn't work either...
      },
     buildDir: "../functions/.nuxt",  // It is this line that breaks it when running locally.

I have the same problem, in localhost only, using npm nuxtjs/firebase with npm firebase and npm firebaseui.

"@nuxtjs/firebase": "^7.1.1",
"firebase": "^8.0.2",
"firebaseui": "^4.7.1",

While it perfectly works in production.
