alpha: Type 'LoadBundleTask' is not generic

[peterpeterparker]

[REQUIRED] Describe your environment

• Firebase SDK version: "firebase": "^0.900.12"

[REQUIRED] Describe the problem

When I try to start my (Stencil) app which I migrated to the Firebase SDK Alpha I get the following error:

[ ERROR ] TypeScript: ./node_modules/@firebase/firestore/dist/exp/index.d.ts:858:53
Type 'LoadBundleTask' is not generic.

L857: /
L858: catch(onRejected: (a: FirestoreError) => R | LoadBundleTask): Promise<R | LoadBundleTaskProgress>;
L859: /*

Happy to help to debug it but not sure where to start.

I also spotted in issue #4381 almost the same exception but in my case, I don't use Timestamp and the msg does not contains much information.

Steps to reproduce:

git  clone https://github.com/deckgo/deckdeckgo/ -b firebase_alpha
cd deckdeckgo/studio
npm ci
npm run start

Relevant Code:

Signin component:

Firebase init:

Auth state change:

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hey, sorry for the late reply, we are working on a fix already: #4207

This should address the issue.

Nice thx for the fix! I'll give it a try when released 🚀
