(422) Unprocessable Entity ERROR

[Anil_Kumar]

I want to log my Exceptions from my .Net Application to the Airtable using the NLog

After configuring the nlog.config file. getting the following error in the Nlog internal logs:

Error WebServiceTarget(Name=ws): Error sending request Exception: System.Net.WebException: The remote server returned an error: (422) Unprocessable Entity.
   at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
   at NLog.Targets.WebServiceTarget.<>c__DisplayClass67_0.<CreateSendContinuation>b__1(IAsyncResult r)

Here is my nlog.config file

<?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"
      throwConfigExceptions="true"
      internalLogLevel="info"
      internalLogFile="c:\temp\internal-nlog-AspNetCore3.txt" >
   <extensions>
    <add assembly="NLog.Targets.Http" />
  </extensions>
  <targets>
     <target type='WebService'
                name='ws'
                url='https://api.airtable.com/v0/BASE_ID/Log?api_key=API_KEY'
                protocol="JsonPost"
            encoding="UTF-8"> 
             <parameter name="fields">

</parameter>
        </target>
    </targets>
    <rules>
