Firestore 1.4.2 in Firebase 6.2.2: array-contains query returns empty array with offline persistence

[henrylearn2rock]

[REQUIRED] Describe your environment

• Operating System version: Win10
• Browser version: Chrome 75.0.3770.100
• Firebase SDK version: 6.2.2
• Firebase Product: firestore

[REQUIRED] Describe the problem

Steps to reproduce:

Make a query with array-contains, no error from console but empty array returned.

Relevant Code:

db
        .collection('Foo')
        .where('barArray', 'array-contains', 'something')

I can confirm this issue.

Downgrading to 6.2.1 (npm install firebase@6.2.1 --save) and the same code returns results.

I have the same issue and I've tried v6.2.1 but it has the same issue too.
Note: When clearing the local storage it works for the first time then getting empty array when back to it again.

[jerryorta-dev]

I downgraded back to v6.2.0, the version I was using before this issue came up. It's still working in that version.

@henrylearn2rock Thank you for reporting this! We will take a look at this shortly. In the meantime, we recommend using an older version.

Unfortunately, we've had no luck trying to reproduce the issue so far, which seems to indicate there are some additional steps necessary for the bug to show up.

Any additional information would be most helpful. In particular:

• a minimal repro case will be super-useful if possible!
• can you please provide logs (please make sure they contain no confidential data) (to enable Firestore logging, use firebase.firestore.setLogLevel('debug');, see docs)?
• does disabling persistence make any difference?
• is there anything interesting about your environment that could affect the results? In particular, are you using anything to package your JS code (say, Webpack)?

a minimal repro case will be super-useful if possible!

how, when it requires building up the collection with proper array index?

can you please provide logs (please make sure they contain no confidential data) (to enable Firestore logging, use firebase.firestore.setLogLevel('debug');, see docs)?

sure, but where can I send it to if we prefer not to post it here?

does disabling persistence make any difference?

YES, disabling offline persistence works as expected. Also, I can reproduce #1904 (comment). I cleared the cache and the query returns the expected results for the first time, but it returns an empty array after a refresh.

is there anything interesting about your environment that could affect the results? In particular, are you using anything to package your JS code (say, Webpack)?

YES, I use Webpack, but I also tried cdn at https://www.gstatic.com/firebasejs/6.2.2/firebase.js and encounter the same bug

Update: we have reproed the issue locally and are searching for the root cause.

We just released v6.2.3 which should fix this problem.

[jerryorta-dev]

confirmed v6.2.3 is working in my environment. Thanks.

[henrylearn2rock]

Oh I just realized firestore is at 1.4.2

yarn add v1.16.0 [1/4] Resolving packages... Couldn't find any versions for "@firebase/firestore" that matches "1.4.3"

Have you released "@firebase/firestore"?

[henrylearn2rock]

also confirmed v 6.2.3 is working now. However @firebase/firestore is still at 1.4.2 https://www.npmjs.com/package/@firebase/firestore.

[hsubox76]

This was a rollback fix, so Firebase 6.2.3 should now have its @firebase/firestore dependency set to 1.4.1. There is no Firestore 1.4.3 yet.
