Kafka Connect Debezium with ms sql server. Key extract configuration problem - apache-kafka

Question

I am working with Debezium and kafka connect. I need to extract "listid" from the payload below and be able to assign it to the kafka message key. Using the configs in my connector file I am unable to extract the value. Appreciate any assistance with solving this.
{
"before": null,
"after": {
"listid": 19,
"billingid": "0",
"userid": "test",
Connector properties
key.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
value.converter=io.confluent.connect.avro.AvroConverter
value.converter.schema.registry.url=http://localhost:8081
transforms=unwrap,extract
transforms.unwrap.type=io.debezium.transforms.ExtractNewRecordState
transforms.extractkey.type==org.apache.kafka.connect.transforms.ExtractField$Key
transforms.extractkey.field=listid
key.converter.schemas.enable=false
value.converter.schemas.enable=true
Sooooo I am continuing to experiment and wanted to share a better explanation of the problem and what I have experimented with.
Following along with Robin's blog https://www.confluent.fr/blog/simplest-useful-kafka-connect-data-pipeline-world-thereabouts-part-3/
1- running kafka-avro consumer from the terminal
KEY
{"LIST_ID":10058}
VALUE
{"before":null,"after":{"test.dbo.test.Value":{"LIST_ID":10058,"billingid
etc...
2- I am trying to get the key to be the value 10058
3 - This is what i have for my transform configuration
key.converter=io.confluent.connect.avro.AvroConverter
key.converter.schema.registry.url=http://localhost:8081
value.converter=io.confluent.connect.avro.AvroConverter
value.converter.schema.registry.url=http://localhost:8081
transforms=createKey,extractInt,
transforms.createKey.type=org.apache.kafka.connect.transforms.ValueToKey
transforms.createKey.fields=LIST_ID
transforms.extractInt.type=org.apache.kafka.connect.transforms.ExtractField$Key
transforms.extractInt.field=LIST_ID
I am using debezium connector in my pipeline against mssql server.

Looks like a typo (extract vs extractkey):
transforms=unwrap,extractkey
transforms.unwrap.type=io.debezium.transforms.ExtractNewRecordState
transforms.extractkey.type=org.apache.kafka.connect.transforms.ExtractField$Key
transforms.extractkey.field=listid
