${label} returned malformed rows
Error message
${label} returned malformed rows What it means
normalizeConversationRows validates the rows array returned by the Grok history-collection script (used by validRows). If the evaluate result is not an array it throws CommandExecutionError('<label> returned malformed rows', 'Expected rows to be an array.'); individual entries must additionally be objects with a valid UUID-shaped Grok conversation id and a valid https://grok.com/c/<uuid> URL.

Solutions
- Confirm the automation browser is authenticated to grok.com and not showing a login or bot-check page, then re-run.
- Retry, or increase --max-scrolls, so the history list fully loads before rows are collected.
- If using a manifestPath instead, verify it is a JSON array exported by grok/export with id and grok.com/c/<uuid> url fields (manifest rows are validated by normalizeManifestRows).
- If it fails on every run, update the opencli Grok collection script — the site's DOM/URL format likely changed.
Example fix
// before (selector drift yields a non-array)
const rows = await page.evaluate(() => document.querySelectorAll('a[href^="/c/"]'));
// after (materialize into an array of plain objects)
const rows = await page.evaluate(() =>
Array.from(document.querySelectorAll('a[href^="/c/"]'), (a) => ({
id: a.href.split('/c/')[1] || '',
title: a.textContent?.trim() || '',
url: a.href,
}))

Strategy: validation
Validate before calling
function looksLikeGrokRows(v) {
const uuid = /^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/i;
return Array.isArray(v) && v.every((r) => r && typeof r === 'object' &&
uuid.test(String(r.id || '')) && /^https:\/\/([a-z0-9-]+\.)?grok\.com\/c\/[0-9a-f-]{36}\/?$/i.test(String(r.url || '')));
} Type guard
function isConversationRowArray(v) {
return Array.isArray(v) && v.length > 0 && v.every((r) => r !== null && typeof r === 'object' && !Array.isArray(r));
} Try / catch
try {
const rows = await collectHistory(page, { offset, limit, maxScrolls });
} catch (err) {
if (err instanceof CommandExecutionError && /malformed rows|malformed row/.test(err.message)) {
// history DOM changed or page not loaded: re-authenticate, raise maxScrolls, or fall back to a manifestPath
return runWithManifest(kwargs.manifestPath, { offset, limit });
}
throw err;
} Prevention
- Pin/track opencli versions and re-verify scraping after Grok UI updates.
- Prefer a manifestPath exported by grok/export (validated by normalizeManifestRows) over live scraping when possible.
- Ensure the history list has loaded (enough scrolls) before collecting rows.
- Reject non-grok.com/c/<uuid> URLs at the data source instead of at validation time.
When it happens
Trigger: collectHistory's page.evaluate returns null/undefined/a non-array (history never loaded, logged-out or bot-check page, evaluate interrupted), or returns an array whose entries are not objects, lack a UUID id, or carry a URL that is not a well-formed grok.com/c/<uuid> link.
Common situations: Grok UI redesign changing the DOM the scraper reads so the script returns a different shape; scraping while signed out or behind a Cloudflare challenge; version drift between the opencli Grok scripts and the live site; a conversation whose URL pattern changed (e.g. different path prefix) failing per-row validation.
Understand the failure class
- Parsing and encoding errors: unexpected token, malformed input — why parsers reject input and how to find the real culprit.
