Failed to confirm add-to-cart success.

Error message

Failed to confirm add-to-cart success.

What it means

CommandExecutionError thrown when result.ok is falsy after all specific reason checks pass — i.e. the button was clicked but the script could not confirm success: neither a Korean 'added to cart' success message appeared nor did the cart count badge increase within the 2500ms wait window.

Solutions

1. Retry the command — if the item actually got added, verify cart contents before re-adding to avoid duplicates
2. Increase the post-click wait time (setTimeout 2500ms) in buildAddToCartEvaluate if confirmations are slow
3. Check the page manually to see what appears after clicking add-to-cart and update the success-message regex /장바구니에 담|장바구니 담기 완료|added to cart/i
4. Verify the cart-count selector still exists in Coupang's current markup

Example fix

// before
 await new Promise((resolve) => setTimeout(resolve, 2500));
// after
 await new Promise((resolve) => setTimeout(resolve, 5000));  // allow slow confirmations

// confirm success by reading the cart after the command
const cartCount = await page.evaluate(() => {
  const n = document.querySelector('[class*="cart"] .count, #headerCartCount, .cart-count');
  return n ? Number(n.textContent.replace(/\D/g, '')) : null;
});

function cartConfirmed(result) {
  return result != null && result.ok === true && Array.isArray(result.items ?? result) === (result.ok === true);
}
// simpler: verify via returned ok flag
function addToCartSucceeded(result) {
  return Boolean(result && result.ok);
}

try {
  const result = await addToCart(page, productId);
} catch (err) {
  if (/Failed to confirm add-to-cart/.test(err.message)) {
    // check the cart before re-adding to avoid duplicates
    const inCart = await checkCartContains(page, productId);
    if (!inCart) await addToCart(page, productId);
    return;
  }
  throw err;
}

When it happens

Trigger: Add-to-cart click succeeded but Coupang showed a confirmation in an unexpected format; confirmation took longer than 2500ms; a modal/interstitial appeared instead of the success message; cart-count selector ([class*="cart"] .count, #headerCartCount, .cart-count) not present so increase couldn't be measured.

Common situations: Slow network making Coupang's confirmation toast late; logged-in state where Coupang opens an option/layer popup after clicking; cart-count element absent in current layout; intermittent anti-bot overlay swallowing the click.
