Shopify Product Page / Home page Bug

Job ID: 39086902

Budget: $30 – $250 USD

My Shopify product page cannot click the "Add to Cart" button, and when debugging, it seems there is an error as shown in the attached image, related to inventory_quantity = ; (no value assigned). I'm not sure how this bug occurred and need your help to find and fix it.

However, this bug does not occur if the customer is logged in or if we try to add the product to the cart from another part of the website and proceed to the checkout page to select a country.

If you need to test, please use Incognito Mode and open this product page:
