Not getting any events from DataStore #2127

Closed skim037 closed 2 years ago

skim037 commented 2 years ago

Description

I started seeing this issue suddenly. There is no changes to my app or schema.

When my app starts, it listens to datastore event like this.

void waitForDataStore() async {
    await Amplify.DataStore.stop();
    await Amplify.DataStore.clear();

    await Future.delayed(const Duration(seconds: 1));
    await Amplify.DataStore.start();

    try {
      // Execute dummy query. (https://github.com/aws-amplify/amplify-flutter/issues/865)
      await profileRepo.getProfile(userId: user.userId);
    } on NoProfileExistsException {
      // Ignore
    } 

    StreamSubscription dsHub =
      Amplify.Hub.listen([HubChannel.DataStore], (hubEvent) {
    });
    dsHub.onData((data) async {
      if (data.eventName == 'ready') {
        await getProfile();
        await dsHub.cancel();
      } 
    });
  }

For some reason, datastore is not sending any events. I have not made any changes as far as I'm aware. No code changes, no recent upgrades, no schema changes. I was wondering if there is something going on from datastore side.

Thanks.

I think I found the issue. I noticed that there were a lot of data accumulated over time while I was testing. It could be that the sync operation took long time and eventually timed out? After deleting the record, the app starts working again.

Before resolving the issue, is there a way to debug this more efficiently? Where can I get logs to investigate issues related to datastore?

Thanks.

Hi @skim037 - sorry you are facing this issue. On iOS, DataStore logs can be viewed most easily by running the app through Xcode. Can you try that and let me know if DataStore was indeed timing out or if there are other issues going on?

skim037 commented 2 years ago

@dnys1 Thanks for the information!. I will give it a try next time I run into Datastore issues. Please feel free to close this issue.

Thanks

Sounds good, thanks @skim037. And please feel free to create another if you run into any more issues.
