Sometimes, when trying to add your bundles to the cart by clicking the add-to-cart button, you might encounter an error message stating "Cannot find variant".
Don't worry! There is nothing wrong with your bundle. This just means that one of the products in your bundle is not available on your shop's online sales channel.
Here's what you can do:
To verify the availability of a specific product on the online sales channel, access your Shopify admin panel.
Navigate to the "Products" section and choose the desired product.
Within the "Publishing" segment, locate the "manage sales channels" option in the menu.
Ensure that the checkbox for "Online Store" is selected.
Another reason for seeing this message is that maybe a product or some of its variants are deleted.
