Shopify Add-to-Cart Error Fix

When a visitor clicks the “Add to Cart” button on my homepage, an error message pops up and nothing is added. The same products can still be added from the catalogue and individual product pages, so the issue is clearly tied to the homepage section or its AJAX call. My theme hasn’t been heavily modified beyond a few styling tweaks, yet this glitch appeared after the last update. I need someone who can jump into the theme files—Liquid, JavaScript, or any cart-related app snippet—and trace the exact cause, then patch it without disrupting the rest of the storefront. Deliverable: a fully functional homepage “Add to Cart” that behaves exactly like the product pages, tested across desktop and mobile. Please tell me about similar Shopify debugging experience you’ve had and how quickly you can start; that’s the key information I’m looking for.
