Current Behavior

The computed paymentChangeable from useOrderDetails is always false, even if the method may be changed.

Expected Behavior

The value of paymentChangeable from useOrderDetails should be true if the payment method on the order can be changed.

Steps To Reproduce

const { loadOrderDetails, paymentChangeable } = useOrderDetails(
  props.orderId,
);
await loadOrderDetails();
paymentChangeable.value // => always false

Environment

No response

Anything else?

checkPromotion is not sent as part of the request body one the readOrder request. Pretty sure this is a regression caused by the following change, as checkPromotion is in mergedAssociations but not mergedAssociations.associations.
