我尝试忽略接收器连接器中的错误消息 errors.tolerance: all 选项。全连接器配置：

{
    "name": "crm_data-sink_pandora",
    "config": {
        "connector.class": "io.confluent.connect.jdbc.JdbcSinkConnector",
        "tasks.max": 6,
        "topics": "crm_account_detail,crm_account_on_competitors,crm_event,crm_event_participation",
        "connection.url": "jdbc:postgresql://dburl/service?prepareThreshold=0",
        "connection.user": "pandora.app",
        "connection.password": "*******",
        "dialect.name": "PostgreSqlDatabaseDialect",
        "insert.mode": "upsert",
        "pk.mode": "record_value",
        "pk.fields": "guid",
        "table.name.format": "pandora.${topic}",
        "errors.tolerance": "all",
        "errors.log.enable":true,
        "errors.log.include.messages":true,
     "errors.deadletterqueue.topic.name":"crm_data_deadletterqueue",
        "errors.deadletterqueue.context.headers.enable":true
    }
}

目标表ddl:

create table crm_event_participation
(
  guid              char(36) not null
    constraint crm_event_participation_pkey
      primary key,
  created_on        timestamp,
  created_by_guid   char(36),
  modified_on       timestamp,
  modified_by_guid  char(36),
  process_listeners integer,
  event_guid        char(36),
  event_response    varchar(250),
  note              varchar(500),
  is_from_group     boolean,
  contact_guid      char(36),
  target_item       integer,
  account_guid      char(36),
  employer_id       integer
);

连接器成功启动，但如果出现错误（例如缺少字段），它将失败。 curl -X GET http://kafka-connect:9092/connectors/crm_data-sink_pandora/status :

请解释一下连接器配置中可能出现的问题？我使用kafka 2.0.0和jdbcsinkconnector 5.1.0。
