Zilla logging needs improvement

[suman-gh-user]

Zilla doesn't log any stack trace if there is any issues occurs it just logs a single error statement which doesn't help to investigate any issues. Also debug logs needs to be improved so that it would be helpful to understand the execution flow and identify exactly where the issue happening and narrow down the problem.

Hi we have the same problem. we dont get any logs from zilla after starting engine. So its a blackbox . Is there any chance to change this and get all logs from engine?
We already implemented and testet a lot like this :
Dockerfile
ENTRYPOINT ["sh","-lc","/home/nonroot/app/zilla start -ve | tee -a /var/log/zilla/engine.log"]
thx
