Description

Hi, on Android when I have already some data in the DataStore and sync is doing updates and some data sync successfully then this error occurs (each time with different model). On iOS it works fine.

I'm creating a new issue according to @Jordan-Nelson comment.

#3580
aws-amplify/amplify-android#2471

The exception you are seeing indicates that AppSync returned no data and no errors. It is expected that AppSync will always return one or the other. I am not sure what would cause this to occur.

How was the back end created (with the Amplify cli, or through some other means)? Do you have conflict resolution enabled? Have you (recently, or previously) made changes to the back end to either change the schema or enable/diable conflict resolution? Do you use any custom resolvers?

hi @Jordan-Nelson

  • with the Amplify cli
  • conflictResolution
"conflictResolution": {
      "defaultResolutionStrategy": {
        "type": "AUTOMERGE"
      }
    },
  • nope
  • I'm not sure but probably no

Some data sync successfully but when IrRecoverableException occurs then sync stop immediately.
Imo in this situation when AppSync return no data and no errors it should continue sync and be able to sync other models.

hi @Jordan-Nelson for now imo it's critical issue, because I cannot sync my datastore on Android without clear it.

@wojciechzahradnikdeviniti - Are you able to reproduce consistently? Are you able to capture the network requests/responses when this occurs? The requests are made from the native Android layer, so they will not show in the Dart dev tools. You could use a tool like Charles proxy to capture them.

@Jordan-Nelson
In my case, AppSync is returning an error. do you have any idea why my dynamodb table fails sometimes to find the index?

{ "data": { "syncCollections": null }, "errors": [ { "path": [ "syncCollections" ], "data": null, "errorType": "DynamoDB:DynamoDbException", "errorInfo": null, "locations": [ { "line": 2, "column": 3, "sourceName": null } ], "message": "The table does not have the specified index: IndexName (Service: DynamoDb, Status Code: 400, Request ID: *****************************************)" } ] }

I have an index created using amplify cli in my Appsync schema model (dynamodb table)

when datastore tries to sync the delta using the lastSync value I get the error The table does not have the specified index
but if I send the same query without the lastSync field the query works

@ridakaddir - Can you confirm this result is the exception you shared in the log above (IrRecoverableException{message=Empty response from AppSync)?

Yes, this happened only on the delta sync because the data I got from AppSync in null with errors.

The delta sync creates a query like

query SyncCollections(
    $filter: ModelCollectionsFilterInput, 
    $lastSync: AWSTimestamp, 
    $limit: Int) 
    {  
        syncCollections(filter: $filter, lastSync: $lastSync, limit: $limit) {    items {
               
            }
            nextToken
            startedAt  
        }
    }

this query sends the lastSync datetime saved in the local DB.

the response

{
  "data": {
    "syncCollections": null
  },
  "errors": [
    {
      "path": [
        "syncCollections"
      ],
      "data": null,
      "errorType": "DynamoDB:DynamoDbException",
      "errorInfo": null,
      "locations": [
        {
          "line": 2,
          "column": 3,
          "sourceName": null
        }
      ],
      "message": "The table does not have the specified index: indexName (Service: DynamoDb, Status Code: 400, Request ID: TT0J07TK989EGNPH3JVMC7RVVVVV4KQNSO5AEMVJF66Q9ASUAAJG)"
    }
  ]
}

if I send the same query again but with lastSync value set to null. the query works

I am having the same problem described here aws-amplify/amplify-android#2564

after approximately 25 minutes the same query with the same lastSync value works.
is it an AppSync issue?

@Jordan-Nelson
I found the root cause of my problem.
amplify cli didn't create an index in the delta table. creating the index manually solved the issue.

@ridakaddir - Thanks for letting me know. If you are able to reproduce that, you can open an issue in https://github.com/aws-amplify/amplify-cli to figure out why that happened.

@ridakaddir - Just to confirm, you are no longer seeing any issue during delta sync?

@ridakaddir - Just to confirm, you are no longer seeing any issue during delta sync?

After manually creating the index for the delta table, the delta API returned the correct data, and the issue with the datastore error was resolved

@wojciechzahradnikdeviniti @ridakaddir - Would either of you being able to confirm that you do not see any issues with delta sync on iOS, even when running the app from Xcode? You may see additional logs when running from Xcode compared to from VSCode/Android studio or flutter run.

On iOS I have also problems with sync using DataStoreSyncExpression and model indexes. IMO this issue can be connected but I cannot see any logs in VSCode.
