This project is a minimal Vue 3 / Quasar / Vite application to reproduce the bug reported in firebase-js-sdk issue #9477.

1. Install dependencies:

   yarn install

2. Configure Firebase: Open the file src/boot/firebase.ts and replace the placeholder Firebase configuration with your actual Firebase project configuration.

   const firebaseConfig = {
     projectId: 'YOUR_PROJECT_ID',
     apiKey: 'YOUR_API_KEY'
   };

3. Create a test document in Firestore: In your Firebase project's Firestore database, create a collection named test-collection and a document with the ID test-doc. The document can have any data, for example a field name with value 'test'.

1. Start the development server:

   npm run dev

2. Open the application in your browser. The application will open automatically at http://localhost:9000.

3. Open the browser's developer console.

4. Click the "Fetch Document" button.

5. Observe the console output. The application will log the DocumentSnapshot.toJSON() and QuerySnapshot.toJSON() output to the console.
