Error message

HTTP ${result.httpStatus} from ${result.where}

What it means

CommandExecutionError thrown when the browser-side fetch of /r/<name>/about.json returns an HTTP status that is not 401/403/404 and not an error envelope — e.g. 429 rate-limit or 5xx. The message includes the numeric status and the endpoint path for diagnosis.

Solutions

1. Wait a minute or two and retry — 429 usually clears once the rate-limit window resets
2. Reduce call frequency / add backoff if scripting many lookups
3. Check https://www.redditstatus.com for a Reddit outage on 5xx statuses
4. Log into reddit.com in the CLI browser session; authenticated requests get higher limits
5. Try from a different network/IP if a shared IP is rate-limited

Example fix

// before
for (const s of subs) reddit subreddit-info ${s} // hammers endpoint, 429
// after
for (const s of subs) { await sleep(1500); reddit subreddit-info ${s} }

if (process.env.REDDIT_RATE_GUARD && Date.now() - lastCallAt < 1500) await sleep(1500);

function isHttpExecutionErr(e){ return e instanceof Error && /^HTTP \d{3} from /.test(e.message); }

try { return await cli.redditSubredditInfo(name); }
catch (e) {
  const m = /^HTTP (\d{3}) from /.exec(e.message);
  if (m && (+m[1] === 429 || +m[1] >= 500)) { await backoffRetry(3); return; }
  throw e;
}

When it happens

Trigger: Reddit's about.json endpoint responding 429 (too many requests), 500/502/503 (server-side outage), or an envelope body with j.error not equal to 404 for reasons other than banned/private/quarantined.

Common situations: Rapid repeated CLI calls tripping Reddit rate limits; Reddit outage windows; aggressive shared-IP scraping (CI runners, VPN exit nodes); WAF interstitials.
