While I can't build the code directly into your app, I can suggest a high-level feature design for a "Smart Authorization Guard" that would help your system handle these errors automatically. Feature Proposal: Smart Authorization Guard
: Instead of a generic error, the feature would log the specific Principal (user) and Resource (topic) that failed, making it much faster for your DevOps team to fix the ACLs (Access Control Lists) . Authorisation Error
: Set your authorizer logs to DEBUG in your broker's log4j.properties to see exactly which user is being denied. While I can't build the code directly into
: If a producer is unauthorized to write to a mission-critical topic, the feature could temporarily route those messages to a safe "quarantine" topic or local storage so no data is lost during the downtime. How to Implement This Today : If a producer is unauthorized to write
: Ensure your Service Account has the WRITE operation allowed on the Topic resource.
: Make sure your JAAS config (username/password/SSL) is correct, as authorization can't happen if the broker doesn't know who you are.
