Missing value for ${arg}

Error message

Missing value for ${arg}

What it means

Thrown by parseArgs when a known flag (--boundary, --trials, or --output) is the last token on the command line with no following value. The parser reads argv[index+1] as the value; if it is undefined/falsy the flag is dangling.

Solutions

1. Provide a value after each flag: `--boundary child`, `--trials 7`, `--output report.json`.
2. Double-check CI scripts and shell aliases for truncated argument lists.

Example fix

// before
node config/scripts/hang-watchdog-memory-benchmark.mjs --boundary
// after
node config/scripts/hang-watchdog-memory-benchmark.mjs --boundary child

// Validate each flag has a value before consuming it
for (let i = 0; i < argv.length; i++) {
  const a = argv[i]
  if (a === '--boundary' || a === '--trials' || a === '--output') {
    if (i + 1 >= argv.length || !argv[i + 1]) throw new Error(`Missing value for ${a}`)
  }
}

When it happens

Trigger: Invoking the benchmark with a trailing flag and no argument, e.g. `--boundary` at end of argv, or `--output` with nothing after it.

Common situations: Typos in CI workflow YAML, a truncated copy-pasted command, or shell quoting that swallowed the value.
