I am trying to enable a purchase.cart-line-item.line-components.render extension in the customiser after deployment of the extensions. But it keeps saying that the app block is not available. In development mode the extension is working fine. I tested this with a really clean UI extension point. Other extension points like 'purchase.checkout.cart-line-item' are working fine.
Steps to reproduce the behavior:
Create a new checkout UI extension
Runnpm run devto check if the extension is showing in a development checkout.
Runnpm run deployto release a new version of the app
After install it is not possible to enable the extension in the customiser.
When you can enable a 'purchase.checkout.cart-line-item' it should also be possible to enable 'purchase.cart-line-item.line-components.render' in the customiser.
