Hi. We see the same error and to my understanding it’s a known error from Amazon. See. https://github.com/awslabs/amazon-kinesis-producer/issues/39#issuecomment-396219522
We don’t have a workaround and haven’t found the reason for the exception. It is one off the reason why we move to Kafka in the near future.
