是否有人已经使用了mongodb的官方mongodb接收器连接器？我尝试使用map remapper后处理器重命名字段，但失败了，目标集合中没有写入任何内容。到目前为止，连接错误日志中没有错误。没有线索。以下是我的连接器的配置：

{
  "value.converter.schema.registry.url": "http://schema-registry:8081",
  "transforms.WrapKey.field": "_id",
  "transforms.WrapKey.type": "org.apache.kafka.connect.transforms.HoistField$Key",
  "name": "mongoDBSink_DbArtists3",
  "connector.class": "com.mongodb.kafka.connect.MongoSinkConnector",
  "key.converter": "org.apache.kafka.connect.storage.StringConverter",
  "value.converter": "io.confluent.connect.avro.AvroConverter",
  "transforms": [
    "WrapKey"
  ],
  "topics": [
    "STR02VWARTISTS"
  ],
  "connection.uri": "mongodb://db:password@mongodb:27017/db?authSource=admin",
  "database": "db",
  "collection": "dbArtists3",
  "post.processor.chain": [
    "com.mongodb.kafka.connect.sink.processor.DocumentIdAdder",
    "com.mongodb.kafka.connect.sink.processor.field.renaming.RenameByMapping"
  ],
  "field.renamer.mapping": "[{\"oldName\":\"key.COUNTRYNAME\",\"newName\":\"CountryName\"},{\"oldName\":\"key.COUNTRYCODE\",\"newName\":\"CountryCode\"},{\"oldName\":\"key.IDALBUMS\",\"newName\":\"IDAlbums\"},{\"oldName\":\"key.GENRE\",\"newName\":\"Genre\"}]",
  "document.id.strategy": "com.mongodb.kafka.connect.sink.processor.id.strategy.ProvidedInKeyStrategy"
}

请确认谁能帮忙，谢谢。
