Unexpected result from reddit subscribed: ${JSON.stringify(r

Error message

Unexpected result from reddit subscribed: ${JSON.stringify(result)}

What it means

If none of the known result kinds matched (not ok/auth/http/malformed/exception) or result.entries is not an array, subscribed.js throws CommandExecutionError including the full JSON of the result. This is a contract check: the browser probe returned an unrecognized shape, so the CLI refuses to guess and surfaces the raw payload for diagnosis. It usually indicates a version mismatch or unexpected Reddit response envelope.

Solutions

Inspect the JSON dumped in the message to see the actual result shape.
Update both the CLI and the browser extension/daemon to matching versions so the sentinel contract holds.
Retry the command — a transient evaluate failure can yield an empty result.
If Reddit changed the payload, patch the scraper's kind/entries contract.

Defensive patterns

Strategy: type-guard

Type guard

function isWellFormedResult(r) {
  return r != null && typeof r === 'object' && typeof r.kind === 'string' &&
    (r.kind !== 'ok' || Array.isArray(r.entries));
}

Try / catch

try {
  await run(['reddit', 'subscribed']);
} catch (e) {
  if (e.message.startsWith('Unexpected result from reddit subscribed:')) {
    const payload = JSON.parse(e.message.slice(e.message.indexOf(':') + 2));
    log.debug('raw result', payload); // diagnose version mismatch
  } else throw e;
}

Prevention

Keep the CLI and its browser extension/daemon on matching versions
Retry transient evaluate failures that yield undefined results
Log the dumped JSON when this occurs to detect contract drift early
Prefer official release channels over mixed-version installs

When it happens

Trigger: page.evaluate resolves to undefined/null or an object without kind/entries (e.g. older browser bridge, script truncated, evaluate failed silently); result.entries missing when kind==='ok'.

Common situations: Mismatched versions of the CLI and its browser extension/daemon; the evaluate promise rejected in a way producing undefined; Reddit returning ok with a differently shaped payload after an API change.
