Hi Team,

We are getting following error in Datagen Connector.

Datagen configuration used is :

{
"connector.class": "io.confluent.kafka.connect.datagen.DatagenConnector",
"schema.string": <schema_string>,
"random.seed": "1",
"name": "datagen_v1",
"kafka.topic": "<topic_name>",
"schema.keyfield": "key",
"max.interval": "1000",
"iterations": "-1"
}

We are using terraform to deploy these connectors. Other Sink and Source Connectors work fine.
