Steps to Reproduce

I think it was either from collection listener or filter query. Happened only once. I'm still trying to reproduce it.

Version of Realm and Tooling

Realm JS SDK - 10.2.0
React Native - 0.63.4
OS: MacOS Catalina 10.15.7
Client OS & Version: iPhone SE 2 Simulator iOS 14.4

The text was updated successfully, but these errors were encountered:

RosenTomov · 2021-02-24T11:32:14Z

Seems to be related to the collection listener. It executes the first time and crashes on subsequent triggers.

realm.objects('Test').addListener(() => { console.log('test'); });

kneth · 2021-03-01T12:03:27Z

@RosenTomov Thank you for the bug report.

Do you only observe it on iOS?

We have recently fixed a couple of logic errors in the notification system and we will try to see if your crash is related.

RosenTomov · 2021-03-01T12:29:50Z

Hello @kneth, the error was caused by a reference to a non-existent object.

ex:

Vehicles: ['1', '2', 'id to non-existent object']

It's been working fine since we removed the id. We didn't get to test it on android.
It was also working fine on our node server before and after removing the referenced id, no errors or anything.

kneth · 2021-03-01T15:26:35Z

You shouldn't see a native crash but a JavaScript exception might be fine.

euZebe · 2021-03-03T09:19:33Z

I get the same error, and can reproduce it on demand. The strange thing to me is that it happens when updating a value. I suppose the object still exists ; it is just mutated.

kraenhansen · 2021-03-03T09:34:51Z

@euZebe great! Would you mind putting together a small project / guide on how to reproduce it?
In particular, we're interested in knowing:

What versions are you using?
What steps are you taking?
What code triggers the error and what schema is the app using?

euZebe · 2021-03-03T10:13:03Z

That's non straight forward since it is an existing project I have just started on. I'll do my best.
Right now, I can tell you

it happens on both versions 10.1.0 and 10.2.0
I am on a form, I update the object with

      realm?.write(() => {
        for (const key in updatedValues) {
          if (updatedValues.hasOwnProperty(key)) {
            const val = updatedValues[key];
            patient[key] = typeof val === 'string' ? val?.trim() : val;
          }
        }
      });

The data is updated successfully, but I have not yet located exactly where the error is occuring.

euZebe · 2021-03-04T20:59:21Z

I went a bit further in the issue: I have a screen with two tabs, one for a patient form (which I can edit) and the other with acts related to this patient. When updating the patient from the form, the app closes and I get the above error.

Here is a piece of code which produces the error:
The Acts tab uses a useActMetadata() hook containing that kind of code:

  useEffect(() => {
    const syncActMetadata = realm.objects<RealmActMetadata>(
      RealmActMetadata.schema.name,
    );
    syncRefByPatient.current = syncActMetadata;

    syncActMetadata.addListener((items, changes) => {   // <== Note: commenting this prevents from crashing
      if (
        changes.deletions.length ||
        changes.insertions.length ||
        changes.newModifications.length
      ) {
        setLastUpdate(new Date());
      }
    });
    setLastUpdate(new Date());

    return () => syncActMetadata.removeAllListeners();
  }, [realm]);

Remarks:

When commenting the .addListener(), updating the patient doesn't provoke a crash.
When putting a ref on another collection, Act (which has the same relationship with the Patient object) instead of ActMetadata, no crash happen.

I tried to reproduce it in a simple example but I did not manage to get the error yet.

julien100 · 2021-03-30T13:29:19Z

I have the exact same issue. If I do an update with

await realm.write(() => { realm.create(Example.schema.name, task, Realm.UpdateMode.Modified); });

and I have an active listener, then my whole app crashes, but change is written.

kneth · 2021-04-09T10:35:57Z

@euZebe Does setLastUpdate() execute a Realm write transaction? If so, your listener might be result in a new call to the listener while still in a write transaction. It shouldn't give you a C++ error but a JavaScript exception.

ironage · 2021-04-09T15:45:32Z

This issue appears to be related to realm/realm-core#4175 and should be fixed in realm-js 10.3.0 or later (the core monorepo releases).

kneth · 2021-04-12T12:05:11Z

@euZebe Please try to upgrade to v10.3.0.

RosenTomov · 2021-04-20T06:36:48Z

We tested it again by manually setting a reference to a non-existent object, now crashes the app and throws the following:

2021-04-20 08:33:13.921467+0300 App[73239:3204065] uncaught exception in notifier thread: N5realm11KeyNotFoundE: No such object
libc++abi.dylib: terminating with uncaught exception of type realm::KeyNotFound: No such object
terminating with uncaught exception of type realm::KeyNotFound: No such object

instead of the original error.

iPhone SE Simulator - iOS 14.4
Mac Mini 2018 - Mac OS Catalina 10.15.7
react-native version - 0.63.4
realm version - 10.4.0

ironage · 2021-04-21T20:00:27Z

Hey @RosenTomov thanks for the update, glad to hear the assertion is fixed.
How/where are you manually setting a reference to a non-existent object? This should not happen in the change listener anymore, so I would like to think that the issue is fixed and the behaviour you observe is related to the way you are manually changing things (through the debugger?). Unless you can provide more information about the the way you are testing and still believe it is a real issue, or this is something you have observed in production?

kneth · 2021-05-13T05:17:53Z

Realm JavaScript v10.4.1 has the fixed mentioned above. I am closing the issue, and if you continue to observe the crash, please create a new issue.
