FIRESTORE (7.14.3) INTERNAL ASSERTION FAILED: value must be undefined or Uint8Array #3096
Description
Describe your environment
- Operating System version: macOS Catalina Version 10.15.4
- Browser version: None
- Node.js version: 12.5.0
- Firebase SDK version: 7.14.4 (implicitly through latest
@firebase/testing) - Firebase Testing SDK version: 0.19.4
- Firebase Product: firestore and testing
- Jest version: 26.0.1
Describe the problem
Steps to reproduce:
Use the code below, then run tests with jest <path-to-your-file>. In my case <path-to-your-file> was ./spec/basic.spec.js.
It seems that firebase.assertFails(...) throws an error and never returns. Jest doesn't exit.
You'll receive the following logs:
(node:18117) PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)
FAIL spec/basic.spec.js

Ran all test suites matching /.\/spec\/basic.spec.js/i.
Jest did not exit one second after the test run has completed.
This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with `--detectOpenHandles` to troubleshoot this issue.
Relevant Code:
Use the following as firestore.rules:
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read: if false;
allow write: if false;
}
}
}
Create a minimal test, reading from a collection:
const firebase = require('@firebase/testing');
describe('Minimal test', () => {
const projectId = 'project-id';
let db;
let ref;
beforeAll(() => {
db = firebase.initializeTestApp({ projectId }).firestore();
ref = db.collection('hello-world');
});
afterAll(() => Promise.all(firebase.apps().map((app) => app.delete())));
test('this tests throws an error and never returns', async () => {
await expect(await firebase.assertFails(ref.get()));
});
});What have I tried
Downgrading @firebase/testing to version ^0.15.0 fixed the issue.
When I tested on my real rules and tests however, it seems to have broken the test reports as setValue is not in const compressedTypes = ['mapValue', 'listValue', 'constraintValue'] in the repost .html function buildValueString(...) yet? This is only speculation! It could be that my rules are simply wrong.
The report .html therefore throws the following error a couple of times:
Found invalid expression-return type.
