Debezium Kafka Connect DROP Table not working - apache-kafka-connect

Question

I have the following setup for implementing CDC using Debezium
Oracle -> Debezium Source Connector -> Kafka -> JDBC Sink Connector -> PostgreSQL
Source Connector config is
{
"name":"myfirst-connector",
"config":{
"connector.class":"io.debezium.connector.oracle.OracleConnector",
"tasks.max":"1",
"database.hostname":"192.168.29.102",
"database.port":"1521",
"database.user":"c##dbzuser",
"database.password":"dbz",
"database.dbname":"ORCLCDB",
"database.pdb.name":"ORCLPDB1",
"database.server.name":"oracle19",
"database.connection.adapter":"logminer",
"database.history.kafka.topic":"schema_changes",
"database.history.kafka.bootstrap.servers":"192.168.29.102:9092",
"database.tablename.case.insensitive":"true",
"snapshot.mode":"initial",
"tombstones.on.delete":"true",
"include.schema.changes": "true",
"sanitize.field.names":"true",
"key.converter":"org.apache.kafka.connect.json.JsonConverter",
"key.converter.schemas.enable":"true",
"value.converter":"org.apache.kafka.connect.json.JsonConverter",
"value.converter.schemas.enable":"true",
"time.precision.mode": "connect",
"database.oracle.version":19
} }
Sink connector config is
{
"name": "myjdbc-sink-testdebezium",
"config": {
"connector.class": "io.confluent.connect.jdbc.JdbcSinkConnector",
"tasks.max": "1",
"topics.regex": "oracle19.C__DBZUSER.*",
"connection.url": "jdbc:postgresql://192.168.29.102:5432/postgres?user=puser&password=My19cPassword",
"key.converter":"org.apache.kafka.connect.json.JsonConverter",
"key.converter.schemas.enable":"true",
"value.converter":"org.apache.kafka.connect.json.JsonConverter",
"value.converter.schemas.enable":"true",
"dialect.name": "PostgreSqlDatabaseDialect",
"auto.create": "true",
"auto.evolve": "true",
"insert.mode": "upsert",
"delete.enabled": "true",
"transforms": "unwrap, RemoveString, TimestampConverter",
"transforms.unwrap.type": "io.debezium.transforms.ExtractNewRecordState",
"transforms.unwrap.delete.handling.mode": "none",
"transforms.RemoveString.type": "org.apache.kafka.connect.transforms.RegexRouter",
"transforms.RemoveString.regex": "(.*)\\.C__DBZUSER\\.(.*)",
"transforms.RemoveString.replacement": "$2",
"transforms.TimestampConverter.type": "org.apache.kafka.connect.transforms.TimestampConverter$Value",
"transforms.TimestampConverter.target.type": "Timestamp",
"transforms.TimestampConverter.field": "dob",
"pk.mode": "record_key"
}
}
Now when I drop a table in Oracle I get an entry in schema_changes topic but the table is not dropped from PostgreSQL. Need help in figuring out the issue why drop is not getting propogated. Just FYI, all the other operations i.e. Create Table, Alter Table, Insert, Update, Delete are working fine. Only DROP is not working and I am not getting any exception in the logs either.
