Unknown argument: ${arg}

Error message

Unknown argument: ${arg}

What it means

Thrown by parseArgs() in scripts/feedback.js when an unrecognized CLI argument is passed. The feedback script only accepts three arguments: --json, --help, and -h. Any other argument is rejected. The script is intentionally minimal — it only prints feedback route URLs.

Solutions

1. Run `node scripts/feedback.js --help` to see the only accepted flags.
2. Remove any arguments other than --json, --help, or -h.
3. If you need to file actual feedback, use the URL the script prints rather than trying to pass it as an argument.

Example fix

// before
node scripts/feedback.js --format json
// after
node scripts/feedback.js --json

const VALID = new Set(['--json', '--help', '-h']);
const invalid = process.argv.slice(2).filter(a => !VALID.has(a));
if (invalid.length > 0) {
  console.error(`Unknown argument(s): ${invalid.join(', ')}. Accepted: --json, --help, -h`);
  process.exit(1);
}

function isFeedbackArg(arg) {
  return ['--json', '--help', '-h'].includes(arg);
}

When it happens

Trigger: Running `node scripts/feedback.js --format text`, `node scripts/feedback.js extra`, or passing any flag/positional other than --json, --help, or -h.

Common situations: A user assumes the feedback script accepts more options (like --format or a message argument) or passes a global flag meant for the main ecc.js CLI to this sub-script instead.
