Debezium sending SQL statements instead of Json objects

[jttully]

I've got the debezium connector attached to a Cloud SQL MySQL database, and the connector is running fine without crashes. However in bigquery I'm seeing a "Failed to serialize json to table row" error, and the payload string's are the SQL statements instead of JSON objects. I was unsure if this was an issue with the pubsub topic/subscription setup, so I tried the dataflow templates for both pubsub topic to bigquery and pubsub subscription to bigquery with the same results. I also tried multi and single topic modes, with the same results.
