MuleSoft Log Forwarding from On-Premise to Splunk

I have a mulesoft on-premise standalone server and i want the applications to forward the logs to splunk , i got the splunk url ( http) with port 8088 (default one)

Url: http://:8088/services/collector/raw

and i deployed a mule app by updating the log4j2.xml under src/main/resources , on the server it throws this error

Tried to followed this article : https://dzone.com/articles/recipe-to-implement-splunk-enterprise-on-premise-f

Added below sections in log4j2 file

 <Http name="Splunk" url="http://xxxx-xxxxx-xxx:8088/services/collector/raw">
            <Property name="Authorization" value="Splunk e052f3fa-xxxxxxxxxx" ></Property>
            <PatternLayout pattern="[%d{MM-dd HH:mm:ss}] %-5p %c{1} [%t]: %m%n"></PatternLayout>
        </Http>

and

 <AsyncRoot level="INFO">
            <AppenderRef ref="Splunk" ></AppenderRef>
        </AsyncRoot>

The error that you see is unrelated to sending logs from log4j2 to Splunk. You have followed the instructions from the link under title "Enabling Splunk on Server Group Using Anypoint Runtime Manager". That part of the article is for sending events from inside the application, through the Runtime Manager Agent to Splunk. That is completely separated from logging. Disable Splunk Event Tracking in Runtime Manager and the error should go away.
