How to resolve ERROR "Failed processing http input"?

[JNgoho]

How can we Stop Docker from sending these logs?
We recently disable the ingestion from Docker to Splunk on the Splunk HEC settings.
But after we disable and delete the HEC settings in Splunk this issue occurs.

We are getting almost 5,000 ERROR every day. 
We try to delete the daemon.json in the docker https://docs.docker.com/config/containers/logging/splunk/

But the docker is still sending error logs.

Hi @JNgoho,

Did you restart the container after deleting the daemon.json file?

We restarted the Docker agent, and still error is sending
