[Firestore] Cannot set properties of undefined (setting 'fromParams')

### [READ] Step 1: Are you in the right place?

**Cloud Firestore support is provided by the [`@google-cloud/firestore`](https://npmjs.com/package/@google-cloud/firestore) library. Therefore the easiest and most efficient way to get Firestore issues resolved is by directly reporting them at the [nodejs-firestore](https://github.com/googleapis/nodejs-firestore) GitHub repo.**

If you still think the problem is related to the code in this repository, then read on.

* For issues or feature requests related to __the code in this repository__
file a Github issue.
* For general technical questions, post a question on [StackOverflow](http://stackoverflow.com/)
with the firebase tag.
* For general Firebase discussion, use the [firebase-talk](https://groups.google.com/forum/#!forum/firebase-talk)
google group.
* For help troubleshooting your application that does not fall under one
of the above categories, reach out to the personalized
[Firebase support channel](https://firebase.google.com/support/).

### [REQUIRED] Step 2: Describe your environment

* Operating System version: macOs Sonoma 14.2.1
* Firebase SDK version: 11.8.0
* Firebase Product: Firestore
* Node.js version: 20.0.0
* NPM version: 9.6.4

### [REQUIRED] Step 3: Describe the problem

#### Steps to reproduce:

What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

You can enable logging for Firestore by including the following line in your code:

```
admin.firestore.setLogFunction(console.log);
```

This will print Firestore logs to the console.

Firestore (6.8.0) 2024-03-18T15:41:13.218Z QLnjt [Firestore._retry]: Retrying request that failed with error: TypeError: Cannot set properties of undefined (setting 'fromParams')

Basically there's a function that runs before starting my express.js app, that function just calls
```
myFunction().then(() => {
app.listen(() => console.log('Server running on port 3000'))
})
```
The function calls
```
fs.collection('myCollection').get()
```

where fs is exported from other file that exports like this

```
import admin from 'firebase-admin'
export const fs = admin.firestore()
```
