could not compile dependency :logger_json, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile logger_json --force", update it with "mix deps.update logger_json" or clean it with "mix deps.clean logger_json"

Elixir 1.16.1 (compiled with Erlang/OTP 26)

The obvious work around is to include Plug as a dep but it seems like LoggerJSON.Formatter.Plug was written to account for its absence.

Fixed in 6.0.1
