Solutions

1. Pass a positive integer, e.g. --limit 20 (max 100).
2. Check the shell variable feeding --limit is set and numeric.
3. Quote/validate inputs in scripts before invoking the command.
4. Omit --limit entirely to use the default of 20.

Example fix

// before
opencli facebook marketplace-inbox --limit "$LIMIT"
// after
LIMIT=${LIMIT:-20}
opencli facebook marketplace-inbox --limit "$((LIMIT > 0 ? LIMIT : 20))"

function parseLimit(raw, fallback = 20) {
  const v = raw ?? fallback;
  const n = Number(v);
  if (!Number.isInteger(n) || n <= 0) throw new TypeError('--limit must be a positive integer');
  return Math.min(n, 100);
}
// run parseLimit(process.argv.limit) before invoking the command

function isValidLimit(v) {
  return Number.isInteger(Number(v)) && Number(v) > 0;
}

try {
  await cli.run(['facebook', 'marketplace-inbox', '--limit', String(limit)]);
} catch (err) {
  if (/--limit must be a positive integer/.test(err.message)) {
    limit = 20; // fall back to default
  } else throw err;
}

When it happens

Trigger: Calling the marketplace-inbox command with --limit 0, a negative number, a non-integer (e.g. 2.5), or a non-numeric string such as --limit abc or --limit '10x'.

Common situations: Shell scripts interpolating empty/unset variables into --limit; users passing floats or strings copied from docs; automation templates with malformed defaults; forgetting that 0 is rejected.
