Full debugging stack trace in production on Fly.io

So I’ve just deployed a Phoenix app on Fly.io and it is behaving differently in production than it is in development. This app is not really in production and it has no users, so I would like to turn on all the console logging and stack traces in production that I would normally see in development. Is this possible?

If you haven’t removed the calls via compile-time config then all you need is to increase verbosity of logger via Logger.config(level: :all).
