无法通过Kafka Connect从MongoDB向neo4j发送数据

我正在尝试使用Confluent社区平台和MongoDB和neo4j连接器将数据从MongoDB发送到neo4j。我使用的是neo4j社区版4.2.3

我将Mongo配置为源，neo4j配置为接收器。以下是我的连接器配置：

curl -X PUT http://localhost:8083/connectors/source-mongodb-test/config -H "Content-Type: application/json" -d '{
      "tasks.max":1,
      "connector.class":"com.mongodb.kafka.connect.MongoSourceConnector",
      "key.converter":"org.apache.kafka.connect.storage.StringConverter",
      "value.converter":"org.apache.kafka.connect.storage.StringConverter",
      "connection.uri":"<my-connection.uri>",
      "database":"data",
      "collection":"test",
      "pipeline":"", 
      "topic.namespace.map":"{\"data\": \"default-topic\", \"data.test\": \"my-mongotesttopic\"}"
}'

然而，我无法将标题输入neo4j。我还尝试将sinkconfig中的cypher查询设置为CREATE（t:Object），当我将数据插入mongoDB时，它创建了一个带有对象标签的简单节点。因此，卡夫卡-->neo4j的连接似乎起作用。我还尝试了不同的方法来定义name属性的内容，如event.title、event.fulldocument.title等，但没有任何效果。在接收器配置中是否有我忘记的东西，或者密码查询是否有问题

提前感谢：-）

因为您使用的是禁用模式的StringConverter或JSON，所以不会提取任何字段
