How do we send multiple records to simulate batch put?

[RichDavis1]

Trying to setup a transformer to process batch records being sent in 15 minute intervals from kinesis.

The process works great utilizing the kinesis-data-generator for a single record but seems to fail when I try and format multiple records.

I've tried formatting the json in the following ways with no success:
[{jsonPayload},{jsonPayload}]

{jsonPayload}, {jsonPayload}

{jsonPayload}{jsonPayload}

Feeling a little lost if anyone knows what I'm doing wrong.
