Description
Raise ticket based on recommendation from
Chris Cranford (Naros)(zulip chat link):
Can you raise a Jira for this @{}Ivan Tsang{} so we can maybe make this configurable. It looks like the behavior is currently hardcoded to return null in this case:
case ARRAY: ArrayNode arrayNode = (ArrayNode) node; return arrayNode.isEmpty() ? null : SchemaBuilder.array(toConnectSchemaWithCycles(key, arrayNode)).optional().build();
In order to make your issue reports as actionable as possible, please provide the following information, depending on the issue type.

What Debezium connector do you use and what version?
Debezium Postgres Connector, 2.4.0 Final
What is the connector configuration?

}
}
What is the captured database version and mode of deployment?
Running local docker-compose with postgres:14.3
What behaviour do you expect?
After inserting this into the value into the `payload` column in my outbox table
{"arrayKey1": [], "key1": "value1", "key2": "value2"}
I expect to see this in my kafka topic message
{
"arrayKey1": [
],
"key1": "value1",
"key2": "value2"
}
What behaviour do you see?
I see this incorrect kafka message
{
"key1": "value1",
"key2": "value2"
}
Do you see the same behaviour using the latest released Debezium version?
yes, I used debezium/connect:2.4.0.Final
Do you have the connector logs, ideally from start till finish?
(You might be asked later to provide DEBUG/TRACE level log)
If needed I can produce.
How to reproduce the issue using our tutorial deployment?
