Thanks for reporting this.

Could you provide more details (error message, exception stack trace) that you are getting?
This is unexpected, as the changes to flink-avro serializers in 1.7.x should be backwards compatible.
More details on how the restore failed will be helpful here.

We are using an AsyncFunction to publish Avro records to SQS. The state for
the AsyncWaitOperator cannot be restored because of serializer changes in
flink-avro from 1.6.3 to 1.7.1.

Any idea how to avoid this problem? Maybe start the job with flink-avro
1.6.3 or will that break other parts?
