Oracle connector Parsing Exception: DDL statement couldn't be parsed

1. Create c##dbzuser  in ORCLCDB (cdb) as explained inside the documentation 2. create two tables with user  c##dbzuser  inside ORCLPDB1 (pdb): create table inbox (id raw(255) not null , timestamp timestamp, primary key (id)) create table outbox (id raw(255) not null , aggregate_id varchar2(255 char ) not null , aggregate_type varchar2(255 char ) not null , payload VARCHAR2(4000 CHAR), timestamp timestamp, type varchar2(255 char ) not null , primary key (id)) 3. Enable SUPPLEMENTAL LOG for outbox table 4. Run connector with below config: config: database.hostname: 192.168.99.108 database.port: 1521 database.user: C##DBZUSER database.password: dbz database.dbname: ORCLCDB database.pdb.name: ORCLPDB1 database.server.name: server10 database.connection.adapter: logminer schema.include.list: C##DBZUSER table.include.list: C##DBZUSER.OUTBOX tombstones.on.delete: false database.history.kafka.bootstrap.servers: my-cluster-kafka-bootstrap:9092 database.history.kafka.topic: schema-changes.outbox poll.interval.ms: 100 5. After the connector is up and running, drop the  inbox table (with user c##dbzuser inside ORCLPDB1 ): drop table inbox cascade constraints; Note:  I have not enabled SUPPLEMENTAL LOG for  INBOX  table and even the INBOX table is not included inside  table.include.list . 6. An exception will be thrown from the connector: 2021-09-02 08:10:04,546 ERROR Mining session stopped due to the {} (io.debezium.connector.oracle.logminer.LogMinerHelper) [debezium-oracleconnector-server10-change-event-source-coordinator] io.debezium.text.ParsingException: DDL statement couldn 't be parsed.
