Describe the bug

I am trying to apply a 100% discount on a one-time payment product.
Applying the code from the dashboard to an invoice does work.
The code is not working in my checkout initialized with the plugin - it works for subscriptions but not for my one-time product purchase
In the logs I see:
POST /v1/checkout/sessions API version [2022-11-15](https://docs.stripe.com/changelog/2022-11-15)
But since apiVersion: '2023-08-16' } the No cost orders have been adde from what I know.
