无法通过NLog保存到ElasticSearch

Question

我有一个受密码保护的ElasticSearch实例。当我尝试在.net core 3.1应用程序中使用NLog.Targets.ElasticSearch直接将日志保存到Elastic搜索时。我出错了。文本日志文件已成功创建。但是条目不会进入弹性搜索。 我的Log .config文件如下：-1：

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true"
      internalLogLevel="info"
      internalLogFile="internalLog.txt">
  <extensions>
    <add assembly="NLog.Web.AspNetCore"/>
    <add assembly="NLog.Targets.ElasticSearch"/>
  </extensions>

  <!-- the targets to write to -->
  <targets>
    <target name="ElasticSearch" xsi:type="BufferingWrapper" flushTimeout="1">
      <target xsi:type="ElasticSearch"
         requireAuth="true"
         username="Rahul"
         password="Test@123"
         uri="http://192.168.52.85:9200"
         index="webapidemo"     />
    </target>

    <!-- write to file  -->
    <target xsi:type="File" name="alldata" fileName="demo-${shortdate}.log"
            layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}" />

    <!-- another file log. Uses some ASP.NET core renderers -->
    <target xsi:type="File" name="otherFile-web" fileName="demo-Other-${shortdate}.log"
            layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}" />
  </targets>

  <!-- rules to map from logger name to target -->
  <rules>
    <!--<logger name="*" minlevel="Info" writeTo="alldata" />-->
    <logger name="*" minlevel="Warning" writeTo="alldata" />
    <!--<logger name="*" minlevel="Info" writeTo="alldata" />-->
    <!--Skip non-critical Microsoft logs and so log only own logs-->
    <logger name="Microsoft.*" maxLevel="Info" final="true" />
    <!-- BlackHole without writeTo -->
    <logger name="*" minlevel="Trace" writeTo="otherFile-web" />
    <logger name="*" minlevel="Debug" writeTo="ElasticSearch" />
  </rules>
</nlog>

我收到以下错误：-
