Cannot save to ElasticSearch via NLog

Elastic Stack Elasticsearch
1

I have a password protected ElasticSearch instance. When i try to use NLog.Targets.ElasticSearch in my .net core 3.1 application to directly save logs to Elastic search. I am getting error.
my Log .config file is as follows.:-1:
'

<?xml version="1.0" encoding="utf-8" ?> 





<!-- 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}" />
'

and i am getting the following error:-

Nlog,config file is as follows:-

<?xml version="1.0" encoding="utf-8" ?> 





<!-- 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}" />
