Error message

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

What it means

CommandExecutionError thrown by `reddit home` when the in-page probe returns kind==='http': /api/me.json or /best.json responded with a non-OK status other than 401/403 (or the /best.json payload lacked a data.children array, reported as HTTP 200 with that note in `where`). It indicates a Reddit-side or protocol-level failure, not a login problem.

Solutions

1. Retry after a delay; check https://www.redditstatus.com if statuses are 5xx.
2. Back off on 429 — reduce poll frequency or add exponential backoff.
3. Read `where` in the message: if it says '/best.json (no data.children array)', the API shape likely changed — update the library or pin a known-good version.
4. Rule out proxy/CDN interference by fetching /best.json from a normal browser on the same network.

Example fix

// before: tight loop
for (const _ of Array(20)) await runHome();
// after: backoff
for (let i = 0; i < 20; i++) { try { await runHome(); } catch (e) { await new Promise(r => setTimeout(r, 2 ** i * 1000)); } }

// health-check the endpoints before the command
const probe = await fetch('https://www.reddit.com/best.json?limit=1&raw_json=1', { credentials: 'include' });
if (!probe.ok && probe.status !== 401 && probe.status !== 403) {
  console.warn(`Reddit degraded (HTTP ${probe.status}); retrying later.`);
}

try {
  const feed = await opencli.reddit.home({ limit: 25 });
} catch (e) {
  if (/HTTP \d+ from/.test(e.message) && attempts < 3) {
    await sleep(2 ** attempts * 5000);
    return retry();
  }
  if (/no data\.children/.test(e.message)) {
    console.error('/best.json shape changed — update the library.');
  }
  throw e;
}

When it happens

Trigger: Reddit returning 429 (rate limit), 5xx (outage/degraded), or 200 with a malformed /best.json payload missing data.children — the message names the exact endpoint via `where`.

Common situations: Polling home too aggressively causing 429s; Reddit incidents returning 5xx; Reddit changing the /best.json response shape (no data.children); CDN edge errors for your region.
