Error message

${label}: ${String(payload.error)}

What it means

requireArrayEvaluateResult validates that an evaluate payload is an array. If instead it is an object with an `error` key, the library throws a CommandExecutionError prefixed with the extraction label and the raw error text. This surfaces in-page failures from shared weibo extraction helpers (called by data/rawData wrappers).

/**
 * `page.evaluate` may return either the raw IIFE value or a
 * `{ session, data }` envelope depending on the browser-bridge version.
 * Adapter code that inspected the payload directly (e.g. `Array.isArray`,
 * truthiness checks on uid strings) silently received the envelope wrapper
 * instead of the inner value. This helper normalizes both shapes so callers
 * can keep their existing checks unchanged.

Solutions

1. Read the `${label}: ...` prefix to identify which extractor failed and what the in-page error said.
2. Re-authenticate the weibo.com session and retry.
3. Retry after a delay if the error indicates rate limiting/anti-bot blocking.
4. Update the CLI if Weibo changed its page structure.

const payload = unwrapEvaluateResult(raw);
if (!Array.isArray(payload)) {
  throw new Error(payload?.error ? `weibo: ${payload.error}` : 'weibo: non-array payload');
}

function isArrayPayload(p) {
  return Array.isArray(p);
}
function payloadError(p) {
  return p && typeof p === 'object' && !Array.isArray(p) && 'error' in p ? p.error : null;
}

try {
  const list = requireArrayEvaluateResult(raw, 'weibo search');
} catch (err) {
  if (String(err.message).includes('malformed')) {
    console.error('Extractor returned bad shape; check login/DOM');
  } else throw err;
}

When it happens

Trigger: Calling a weibo data/rawData command whose injected script returned {error: '...'} instead of an array; the label in the message identifies which extractor failed.

Common situations: Weibo rate-limiting or anti-bot interstitials cause the in-page script to report an error; login expired; the extractor's target element is missing after a Weibo UI update.
