title: Amazon Kinesis: Caught exception while sync'ing Kinesis shards and leases
body: <p>I am trying to make <a href="https://github.com/snowplow/snowplow" rel="noreferrer">Snowplow</a> work on AWS. When I am trying to run stream-enrich service on instance, I am getting this exception:</p>
  
  <pre><code>[main] INFO com.amazonaws.services.kinesis.clientlibrary.lib.worker.Worker - Syncing Kinesis shard info
  [main] ERROR com.amazonaws.services.kinesis.clientlibrary.lib.worker.ShardSyncTask - Caught exception while sync'ing Kinesis shards and leases
  [cw-metrics-publisher] WARN com.amazonaws.services.kinesis.metrics.impl.CWPublisherRunnable - Could not publish 4 datums to CloudWatch
  </code></pre>
  
  <p>I don't think error is due to Cloud Watch:</p>
