Error message

coupang product extraction failed: ${error?.message || error}

What it means

Wraps a failure of page.evaluate(buildProductDetailEvaluate(productId)) — the in-page DOM extraction script for the Coupang product detail. If the evaluation script throws or the browser command fails, it is rethrown as a CommandExecutionError with this message.

Solutions

Re-run the command after confirming the product page loads and renders in a normal Chrome window.
Complete any captcha/login interstitial in the connected Chrome profile, then retry.
Increase the browser command timeout if evaluate is timing out.
Update the CLI if Coupang changed its DOM (check for a newer version fixing extraction selectors).

Defensive patterns

Strategy: retry

Validate before calling

// sanity-check the target page exists before extraction
const res = await fetch(productUrl, { method: 'HEAD' });
if (!res.ok) throw new Error(`product URL returned HTTP ${res.status}`);

Try / catch

try {
  return await run('coupang product', { url });
} catch (err) {
  if (err?.code === 'COMMAND_EXEC' && /extraction failed/.test(err.message)) {
    // page likely didn't render or a captcha appeared; retry after a pause
    await sleep(3000);
    return await run('coupang product', { url });
  }
  throw err;
}

Prevention

Complete any captcha/login interstitial in the connected Chrome profile first.
Ensure the page fully renders in a normal browser before automating it.
Keep the CLI updated for Coupang DOM changes.
Use one retry with delay rather than hammering the page.

When it happens

Trigger: `opencli coupang product` where the in-page evaluate fails: page did not render (still on error/captcha page so expected DOM missing and script throws), page closed or navigated mid-evaluate, script execution blocked by CSP, or browser command timeout.

Common situations: Coupang showing a bot-detection/captcha interstitial instead of the product page; very slow render causing evaluate on an incomplete document; extension disconnected mid-command; Coupang DOM changes crashing a selector access inside the evaluate script.
