      For bug reports, provide this information, please:

      What Debezium connector do you use and what version?

      Debezium oracle connector 1.9.6.Final

      What is the connector configuration?

      "name": "_DebeziumSource_375""config": {    "connector.class": "io.debezium.connector.oracle.OracleConnector",    "database.user": "*******",    "database.dbname": "*****",    "tasks.max": "1",    "database.history.kafka.topic": "history_375",    "database.history.kafka.bootstrap.servers": "******",    "database.server.name": "_server_375",    "event.processing.failure.handling.mode": "fail",    "column.include.list": "******",    "log.mining.strategy": "online_catalog",    "database.port": "*****",    "decimal.handling.mode": "string",    "database.hostname": "*******",    "database.password": "6QAwUcVS43",    "name": "_DebeziumSource_375",    "table.include.list": "*********",    "snapshot.mode": "initial"  },  "tasks": [{ "connector": "_DebeziumSource_375", "task": 0 }],  "type": "source"}
       

      What is the captured database version and mode of depoyment?

      (E.g. on-premises, with a specific cloud provider, etc.)

      oracle 11g logminer

      What behaviour do you expect?

      Snapshot should be done successfully

      What behaviour do you see?

      NullpointException was thrown.

      Do you see the same behaviour using the latest relesead Debezium version?

      (Ideally, also verify with latest Alpha/Beta/CR version)

      have not tested yet

      Do you have the connector logs, ideally from start till finish?

      (You might be asked later to provide DEBUG/TRACE level log)

      How to reproduce the issue using our tutorial deployment?

      set up source database with Rule Manager and Expression Filter

      when the following table in the database, NPE will be thrown when executing snapshot
