Coraza SPOA Error: "response id is empty"

[Mkiings]

Hi everyone,

I'm running Coraza SPOA on a HAProxy VM and encountering a recurring error in the logs:

root@haproxyvm:~/coraza-spoa# tail -f /var/log/coraza-spoa/coraza-agent.log
3:44PM PNC Error handling request error="response id is empty"
3:44PM PNC Error handling request error="response id is empty"
3:44PM PNC Error handling request error="response id is empty"
3:44PM PNC Error handling request error="response id is empty"
3:44PM PNC Error handling request error="response id is empty"
3:54PM PNC Error handling request error="response id is empty"
3:54PM PNC Error handling request error="response id is empty"
3:55PM PNC Error handling request error="response id is empty"
4:10PM PNC Error handling request error="response id is empty"
4:15PM PNC Error handling request error="response id is empty"
This error keeps appearing, and I suspect it might be related to SPOA's communication with HAProxy.

My setup:
HAProxy Version: version 2.8.13
Coraza-SPOA Version: Core version (v3.2.2)
OS: Debian 12 (Bookworm)
Deployment: Running Coraza-SPOA as a service on HAProxy VM
Configuration Details:
HAProxy and Coraza-SPOA are communicating over a Unix socket
No firewall rules blocking communication
HAProxy is properly configured with the SPOA settings
Steps I've Tried:
Checking permissions
Verifying HAProxy and SPOA configuration
Ensuring the Coraza agent process is running
Despite these, the issue persists.

Has anyone encountered this before? Any ideas on what could be causing it or how to debug further?

Thanks in advance!
