title: Dynamodb stream kinesis - Incomplete hash range found between
body: <p>I have kinesis stream from DynamoDB. And I am processing it through aws KCL sdk v1.14.0. I see below occasional errors in the logs. I also observe that startingHashKey is always 1 and endingHashKey is 0 for all shards in the dynamodb lease table. Any clue why is this happening?</p>
