Troubleshooting: Error Writing Log to Kafka Producer (NullReferenceException)

Version Affected: Cloud Deployment Connectors only
 
 

Overview

The following error appears repeatedly in the nlog-internal.log file on a Cloud Deployment Connector:

Error Error writing log to Kafka Producer Exception: System.NullReferenceException: Object reference not set to an instance of an object.
at SecureAuth.Agent.Service.NLogAppenders.KafkaAppender.Write(LogEventInfo logEvent) in C:\jenkins_slave_nodes\workspace\Core_Builds_agent_master\src\SecureAuth.Agent.Service\NLogAppenders\KafkaAppender.cs:line 84

This error is specific to Cloud Deployment Connectors and does not apply to other appliance types.

 

Cause

This error has no actual functional impact on the Connector. It is logged because the cacert.pem file is missing from the Connector's installation folder. This file is present by default, but antivirus software on the Connector server can sometimes flag and remove it. 

Resolution

To resolve this:

1. Check your other Cloud Deployment Connector servers to see if the cacert.pem file is present elsewhere.
2. If it is, copy that file to any Connector server that is missing it, then restart the service. The error will no longer appear in the log.
3. If none of your Connector servers have the cacert.pem file, contact SecureAuth Support, who can provide a copy of the file.
