嗨，我正在尝试使用morphline inteceptor并将我的syslog转换为json作为开始我尝试使用split命令来分割我的字符串，但我得到如下错误：
“”由于在配置com.typesafe.config.configexception$wrongtype:/root/flume.17/conf/morph.conf:21时出错，源r1已被删除：无法将对象或列表与非对象或列表、configstring（“split”）和simpleconfigobject（{“outputfields”：“substrings”、“inputfield”：“message”、“addemptystrings”：false、“isregex”：false连接起来，“trim”：true，“separator”：“}）不兼容“”
我的行配置文件：

morphlines : [
{

# Name used to identify a morphline. E.g. used if there are multiple

# morphlines in a morphline config file

id : morphline1

# Import all morphline commands in these java packages and their

# subpackages. Other commands that may be present on the classpath are

# not visible to this morphline.

importCommands : ["org.kitesdk.**"]

commands : [
  {
    # Parse input attachment and emit a record for each input line              

readLine {
      charset : UTF-8
    }
  }

  ,split {
  inputField : message
  outputFields : "substrings"     
  separator : " "       
  isRegex : false     

  addEmptyStrings : false
  trim : true          }
       }
      }

   ]
  }
 ]

我该怎么办？我是新手
