Reddit whoami failed: ${result.detail}

Error message

Reddit whoami failed: ${result.detail}

What it means

CommandExecutionError thrown when the in-page IIFE inside verifyRedditIdentity throws and returns {kind:'exception'}. The browser-side fetch/JSON parse of /api/me.json failed, and its message is surfaced here. It is a client-side (in-page) execution failure rather than a documented Reddit status.

Solutions

  1. Re-run the command; transient network/navigation races often clear on retry.
  2. Check what the browser actually renders at reddit.com — a block/quarantine page means the JSON parse failed; solve the block first.
  3. Ensure no concurrent navigation or page.close() happens while verifyRedditIdentity is evaluating.
  4. Test network from the automation browser directly; fix proxy/TLS issues if fetch fails at the network layer.

Example fix

// before: evaluate racing a navigation
await Promise.all([page.goto('https://www.reddit.com/'), verifyRedditIdentity(page)]);
// after: sequence the calls
await page.goto('https://www.reddit.com/');
await verifyRedditIdentity(page);
Defensive patterns

Strategy: try-catch

Validate before calling

// ensure the page is alive and settled before evaluating
await page.goto('https://www.reddit.com/', { waitUntil: 'load' });
if (page.isClosed?.()) throw new Error('page closed before probe');

Try / catch

try {
  const me = await opencli.reddit.whoami();
} catch (e) {
  if (/Reddit whoami failed/.test(e.message)) {
    console.error('In-page probe failed:', e.message); // inspect detail, retry or check network
  }
  throw e;
}

Prevention

When it happens

Trigger: The fetch itself rejects inside the page context: network error/TLS failure, page navigated mid-evaluate killing the async fetch, CORS/context issues, or res.json() throwing on a non-JSON body (e.g. an HTML block page).

Common situations: Reddit serving a quarantine/block interstitial HTML instead of JSON; flaky network in the automation browser; page.close() or navigation racing the evaluate; corporate MITM proxy breaking TLS.
