-v does not take a value in this CLI. It is a counter flag, so Clap parses extra words like DEBUG, INFO, 1 as unexpected positional arguments.

Use repeated v flags instead:

ssserver.exe -c config.json        # default, level 0
ssserver.exe -c config.json -v     # level 1 / debug for shadowsocks modules
ssserver.exe -c config.json -vv    # level 2 / trace for shadowsocks modules
ssserver.exe -c config.json -vvv   # more verbose trace

The code defines it as ArgAction::Count, and the logger maps the count roughly like this:

• 0: normal/info for shadowsocks modules
• 1: debug
• 2: trace
• 3+: very broad trace

If you prefer config file syntax, the same setting is:

{
  "log": {
    "level": 1
  }
}

So the equivalent of your attempted -v DEBUG is probably just -v; for maximum logs use -vv or -vvv.
