How do you handle java.lang.IllegalStateException at RealAppSyncCall.java:350

Let me investigate this and get back to you.

@olga-dorogan

The mutation queue handling logic is intended to be a sequential pipe, executing mutations one at a time. There were, however, synchronization issues and race conditions that were causing the same mutation to be tried more than one thread concurrently, which resulted in this exception.

Version 2.7.1 of the SDK contains synchronization and threading model changes that fixes this issue.
See the following for a test that shows 25 mutations issued in a rapid fire fashion that is then validated for sequential execution

aws-mobile-appsync-sdk-android/aws-android-sdk-appsync-tests/src/androidTest/java/com/amazonaws/mobileconnectors/appsync/AWSAppSyncQueryInstrumentationTest.java

Line 838 in c2dbc52

public void testMultipleOfflineMutations() {

Please upgrade to v2.7.1 and let us know how you fare.

Closing as I haven't heard back. Please feel free to post here or create a new thread if still facing issues.

Hello.

We've caught very similar exception with similar stacktrace on executing a lot of mutations but on AppSync 2.7.8:
