V2 common log format not working?

I have perms. This was working perfectly under caddy v1. I’ve been updating the Caddyfile to work with v2 and this seems to be the only sticking point.

Also, the default log writes to stderr unless configured otherwise. So you’ll still see access logs there since all logs write from all loggers by default.

I don’t understand. It’s writing INFO and ERROR msgs to the same place (my terminal). Nothing at all is going to the file. What do I have to do to get it to all go to the file, and in the old common log format?
