Why is the selling plan missing in my checkout line items?

Im trying to get the the selling plan of the each product in my checkout with below code. I’m getting empty. it works with orders.line_items ( available only in status page)

{% for line_item in checkout.line_items %}
console.log(“v”,JSON.stringify(“{{ line_item.variant.selected_selling_plan_allocation.selling_plan.name }}”))
console.log(JSON.stringify(“{{ line_item.selling_plan_allocation.selling_plan.name }}”))
console.log(JSON.stringify(“{{ line_item.selling_plan_allocation }}”))
{% endfor %}

I also have the same issue. Cannot access selling plans via Liquid on checkout.
