我尝试使用restapi调用创建kafka connect spooldir源连接器。启动zookeeper和kafka服务器，并使用 kafka/bin/connect-distributed.sh dir-distributed.properties ，我从postman调用了以下api：

POST http://localhost:8083/connectors

{
    "name": "csv-source-orders",
    "config": {
        "connector.class": "com.github.jcustenborder.kafka.connect.spooldir.SpoolDirCsvSourceConnector",
        "tasks.max": "1",
        "topic": "orders",
        "input.file.pattern":"^orders.*.csv$",
        "input.path":"/Users/ivij/temp/source",
        "finished.path":"/Users/ivij/temp/finished",
        "error.path":"/Users/ivij/temp/error",
        "halt.on.error": "false",
        "csv.separator.char":"01",
        "value.schema":"{\"name\":\"com.github.jcustenborder.kafka.connect.model.Value\",\"type\":\"STRUCT\",\"isOptional\":false,\"fieldSchemas\":{\"order_id\":{\"type\":\"INT64\",\"isOptional\":false},\"customer_id\":{\"type\":\"INT64\",\"isOptional\":false},\"order_ts\":{\"type\":\"STRING\",\"isOptional\":false},\"product\":{\"type\":\"STRING\",\"isOptional\":false},\"order_total_usd\":{\"type\":\"STRING\",\"isOptional\":false}}}",
        "key.schema":"{\"name\":\"com.github.jcustenborder.kafka.connect.model.Key\",\"type\":\"STRUCT\",\"isOptional\":false,\"fieldSchemas\":{\"order_id\":{\"type\":\"INT64\",\"isOptional\":false}}}",
        "csv.first.row.as.header": "true",
        "flush.size": "100",
        "rotate.interval.ms": "1000"
    }
}

响应状态为 201 Created 一条新资源已创建的消息。但在响应主体中，tasks字段为空：

"tasks": [],
    "type": "source"

当我尝试检查连接器的状态或使用列出连接器时 GET localhost:8083/connectors/ 收到的响应是 [] .
我还尝试列出在端口8083上创建的主题（以检查是否创建了api json中的“orders”主题），但这会导致outofmemory错误。
正在创建连接器吗？我如何解决这个问题？
编辑：以下是“dir distributed.properties”文件：
