logs are missing corresponding entries captured in default Caddy access.log

[glenstewart]

Using Caddy 2.6.2, I see that many entries are missing from the Common and/or Combined log output, which are captured when I switch back to the normal access.log.

I am guessing something changed (lately) in Caddy, and the transform-encoder doesn't know how to handle it.

Please be more specific. Which logs? What do they look like before and after? Try to isolate it to individual requests. What's the config you used, etc.

For example, access.log will show this:

{"level":"debug","ts":"24/Nov/2022:16:11:45 +0000","logger":"http.log.error","msg":"{id=s4kv4f6v5} fileserver.(FileServer).notFound (staticfiles.go:579): HTTP 404","request":{"remote_ip":"192.168.1.3","remote_port":"38556","proto":"HTTP/2.0","method":"GET","host":"welovegod.org:8443","uri":"/js/default.js","headers":{"Sec-Ch-Ua-Platform":["\"Linux\""],"Sec-Fetch-Site":["same-origin"],"Sec-Fetch-Mode":["no-cors"],"Cookie":[],"Sec-Gpc":["1"],"User-Agent":["Mozilla/5.0 (X11; U; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/106.0.5172.138 Safari/537.36"],"Accept-Encoding":["gzip, deflate, br"],"Referer":["https://welovegod.org:8443/recipes"],"Sec-Fetch-Dest":["script"],"Accept-Language":["en-US,en;q=0.9"],"Dnt":["1"],"Sec-Ch-Ua-Mobile":["?0"],"Accept":["/"],"Sec-Ch-Ua":["\"(Not(A:Brand\";v=\"99\", \"Chromium\";v=\"106\", \"Google Chrome\";v=\"106\""]},"tls":{"resumed":false,"version":772,"cipher_suite":4865,"proto":"h2","server_name":"welovegod.org"}},"duration":0.000078285,"status":404,"err_id":"s4kv4f6v5","err_trace":"fileserver.(FileServer).notFound (staticfiles.go:579)"}

...but the site_combined.log will show no entry. I can tail -f site_combined.log and hit the server with good and bad requests, and only occasionally (in the first minutes after the server starts) will any logging happen - then it goes silent.

[francislavoie]

Those are http.log.error, i.e. not access logs which are http.log.access. They're a different category of log message. This encoder isn't meant to handle these.

(Closing, unless there's something actionable here. If so, please post a config and instructions to minimally-reproduce the issue so we can look at fixing it. Thanks!)
