btw, your original sample works as intended for me it seems like:

dnscheck on  main [!] via  
→  elixir -e 'require Logger; Logger.configure_backend(:console, device: :standard_error); Logger.error("why stdout?")' 2>scr/delme

dnscheck on  main [!] via  
→  cat scr/delme

18:55:55.984 [error] why stdout?

Perhaps due to elixer/erlang versions being used?
I’m on:
