Coupon code feature is not working properly in the checkout page on Magento 2.4.7

[TuVanDev]

Preconditions and environment

• Magento version: 2.4.7
• The checkout page only contains "Review & Payments" step as the cart only contains virtual or/and downloadable product types.

Steps to reproduce

Example:

1. Create a Virtual/Downloadable product.
2. Navigate to storefront as a guest.
3. Click “Add to Cart” on the Virtual/Downloadable Product.
4. Open mini shopping cart and click “Proceed to Checkout”.
5. Click "Apply Discount Code" text to expand the coupon code form.

Expected result

The discount code/coupon input can be filled in, and the button title text displays as "Apply Discount".

Actual result

The discount code/coupon input is disabled, and the button title text displays as "Cancel coupon".

Additional information

It's important to note that I've tested this issue on Magento 2.4.6 and it didn't occurs.

Hi @TuVanDev the file attached is a patch file that seems to resolve the issue. I have looked at Magento develop branch and previous Magento versions and this file has not changed in a while. That means this may not address the root of the issue. However, the patch change is low risk and I hope it may be sufficient to get this problem addressed discount-issue.zip

[TuVanDev]

Hey @digitalrisedorset, thanks for your assist.

Yep, the code isApplied(couponCode() != null); in the file vendor/magento/module-sales-rule/view/frontend/web/js/view/payment/discount.js hasn't changes for years. It now has an empty value instead of null. Therefore, isApplied(couponCode() != null); should be changed to isApplied(couponCode() !== '');

I'll try to find the root cause and confirm if this is the best solution for this issue.

FYI, you can post the patch in your comment instead of sharing a zip file for more visibility.

the patch file code is:

     return Component.extend({

However, this will break the feature if the cart contains an item that is not virtual. Therefore, I've investigated and found the root cause of the issue. I'll create a pull request soon!
