selectedDeliveryOption is always null in the input to function

[SaeedYasin]

Here is the checkout, where I have tried to select a delivery option and reload checkout, it does seem to remember what delivery option I selected last time.

But selectedDeliveryOption in the input to the function is always null, no matter what I try, it is never set to any value other than null.

Is this a known issue? or am I doing it wrong some how? 👀

This only happens in delivery customizations, but works fine in payment customizations.

I'm getting deliveryGroups in my discount function, and it always returns empty array. The same here

Hey,

Any solutions to this problem ?

[aldoalprak]

is there any update on this? the bug still exists until now

I had a conversation with someone at Shopify, and they explained that the delivery customization function operates even before the user selects a delivery option, which is why it returns null. This makes sense, as it’s necessary to display only the relevant delivery options.

I suggest they update the documentation to clarify this and remove the mention of the selected delivery option, as it is leading to confusion among developers.
