'FIRESTORE INTERNAL ASSERTION FAILED: Unexpected state' when unit testing with Jest

I'ḿ setting up a jest test suite for a Node.js and Express REST API i'm building, i'm using @firebase/testing module to initialize a testing app, however when i try to perform any sort of operation to the database this error comes out:

FIRESTORE (7.17.2) INTERNAL ASSERTION FAILED: Unexpected state
      at fail (/home/cardonapablo/Documentos/Proyectos/Optica (Ilicit)../../../../../node_modules/@firebase/testing/node_modules/@firebase/firestore/src/util/assert.ts:39:9)

I also tried connecting to my regular firestore database with the credentials i have been using to develop the endpoints and same error pops out even tho it's the app i use daily

Weird thing is, data is being written to the database, but error still stops testing

Here is firebase setup:

(src/db/functions.js)

let app  = initializeTestApp({ 
    projectId: "illicit"
})
db = app.firestore()
module.exports = { db }

Function throwing the error

(tests/fixtures/db.js)

const { db } = require('../../src/db/functions')
const bcrypt = require('bcrypt');

const createAdmin = async function() {

    // Encrypt password
    let encPass = await bcrypt.hash("admin", 8)

    let admin = {
        name: "Admin Test User",
        email: "[email protected]",
        password: encPass,
        tokens: []
    }

    // Add to db
    let docRef = await db.collection('admins').add(admin) // <- This line throws the error
    return;
}

module.exports = {
    createAdmin
}

And finally testing file

(tests/glasses.test.js)
const supertest = require('supertest');
const app = require('../src/app')
const functions = require('./fixtures/db')

let adminToken;
let glassesId;

//Executes before any test, here is where error occurs, before any tests
beforeAll( async () => {
    await functions.createAdmin()
    return
})

test('Should log in an admin', async () => {
    let response = await supertest(app)
    .post('/admins/login')
    .send({
        email: '[email protected]',
        password: 'admin'
    })
    .expect(200);
    expect(response.body.token).toEqual(expect.any(String))
    adminToken = response.token;
});

This only happens only when i try to test, regular app works just fine

Things i've tried:

Hope you can help me :)

This is a open issue on GitHub. I'm pasting my comment from that issue here to hopefully help some other people:

I experienced the same error message on 9.6.6 with NextJS. I believe this error message could be presented due to a range of errors - as I see 100+ Stackoverflow questions with this error message.

After lots of debugging I realized I accidently used SQL capitalization:

.orderBy('time', 'ASC') = "INTERNAL ASSERTION FAILED: Unexpected state" .orderBy('time', 'asc') = No Errors!

This was a pain to debug, and my mistake was so small. Maybe better error reporting is needed in cases like this? When you get then Google this error message it easily leads you down a path of debugging things completely irrelevant to the real error.

So pretty much - a tiny syntax error can cause the error message and lead you down a road of debugging the wrong things. To solve this you have to find exactly where it is happening and narrow in your debuging.

You should change Jest's test environment from the default jsdom to node using jest --env=node or by setting the testEnvironment option to node in your Jest config.

Solved the problem myself, i was using the Firebase web client, I switched to the Admin SDK made specifically for servers, i guess it was some sort of auth problem, because the admin sdk automatically authenticates you in the db
