Purpose

When using akka-stream-alpakka-elasticsearch and akka-stream-alpakka-kinesis in the same project, the following error will get swallowed:

Exception in thread "main" java.util.concurrent.ExecutionException: com.amazonaws.SdkClientException: Unable to marshall request to JSON: Jackson jackson-core/jackson-dataformat-cbor incompatible library version detected.
You have two possible resolutions:
		1) Ensure the com.fasterxml.jackson.core:jackson-core & com.fasterxml.jackson.dataformat:jackson-dataformat-cbor libraries on your classpath have the same version number
		2) Disable CBOR wire-protocol by passing the -Dcom.amazonaws.sdk.disableCbor property or setting the AWS_CBOR_DISABLE environment variable (warning this may affect performance)

[2m]

Instead of adding an additional logging statement, we should pass in the exception to the above statement:

log.error(ex, "Failed ...", shardId)

Thanks. LGTM!
