Error message

coupang add-to-cart navigation failed: ${error?.message || error}

What it means

This CommandExecutionError wraps a failure of page.goto(finalUrl) during the coupang add-to-cart flow. The Playwright navigation itself rejected (timeout, net::ERR_*, navigation interrupted) and the library catches it and rethrows with the underlying message. It means the browser never successfully loaded the product page, so the add-to-cart script could not run.

Solutions

1. Read the wrapped error message for the root cause (net::ERR_NAME_NOT_RESOLVED, Timeout 30000ms exceeded, etc.) and address that specifically
2. Increase the navigation timeout: page.goto(finalUrl, { timeout: 60000, waitUntil: 'domcontentloaded' }) in your wrapper or pass a larger timeout to the command if supported
3. Verify the product id/URL is valid — navigate manually in Chrome to confirm the product page loads
4. Check network/proxy/VPN issues and ensure the Chrome instance the command drives has internet access

Example fix

// before
await page.goto(finalUrl); // flaky timeout on slow network
// after
await page.goto(finalUrl, { timeout: 60000, waitUntil: 'domcontentloaded' });

const productId = '1234567890';
if (!/^\d+$/.test(productId)) throw new Error('product-id must be numeric digits');
const probe = await fetch(`https://www.coupang.com/vp/products/${productId}`, { method: 'HEAD' });
if (!probe.ok) throw new Error(`product page not reachable: HTTP ${probe.status}`);

function isNavFailure(e) {
  return /add-to-cart navigation failed|net::ERR|Timeout \d+ms exceeded/i.test(e?.message || '');
}

try {
  await runCli('coupang add-to-cart', '--product-id', productId);
} catch (e) {
  if (isNavFailure(e)) {
    await new Promise(r => setTimeout(r, 5000));
    return runCli('coupang add-to-cart', '--product-id', productId);
  }
  throw e;
}

When it happens

Trigger: `page.goto(finalUrl)` rejects: network timeout (default 30s), DNS failure, connection reset, net::ERR_ABORTED from a redirect/download, invalid finalUrl produced by canonicalizeProductUrl from a malformed --url, or the browser/page being closed mid-navigation.

Common situations: Slow or blocked network, Coupang bot protection aborting the navigation, a malformed product URL string passed as --url that canonicalization couldn't fix, page closed by prior code, or flaky corporate proxy causing timeouts.
