Troubleshoot Cluster Linking on Confluent Platform

This page describes common errors you may encounter when creating cluster links, and how to address them. Task error codes for cluster link and mirror topic commands are also listed.

Troubleshoot and Task Error Codes

The following error codes are shared by cluster link and mirror topic commands to indicate problems with the link tasks or the mirror transition tasks.

With the exception of INTERNAL_ERROR, these are all user-created errors. In other words, if the error code is INTERNAL_ERROR, then Confluent will have been alerted and will be working on fixing the issue. Otherwise, the error is customer created and the customer can and should alert on, as the error requires customer action to resolve.
