From October 2023, when you make a product from a bundle with this setting:
You may notice the following error message when you go to Shopify admin > Products section for that bundle as a product.
Not to worry!
We've introduced a new feature to ensure that every newly created bundle-as-a-product, with the mentioned setting, is correctly added to the cart with the right items and variants, preventing any incorrect additions (For more information about this issue you can check this article). While Shopify may still display an error message as it's adapting to this release, rest assured, you can safely disregard it. This update aims to prevent any mishaps during the add-to-cart process.
We've got you covered
It's important to note that while we're working diligently to prevent any issues for all app users, it's not currently active for every shop. This new feature is only applicable to shops utilizing the "Shopify Bundles" feature. If your shop doesn't have this feature activated, you can still rely on the previous solution, known as the "Invalid BAP modal popup,".
