Action ${associatedAction.id} is not adding a shipping metho

Error message

Action ${associatedAction.id} is not adding a shipping method

What it means

Second phase of draft-order shipping action validation: the action exists but its type is not SHIPPING_ADD, so it cannot be treated as a shipping-method addition (e.g. for removal or amount update).

Solutions

1. Check action.action === 'SHIPPING_ADD' before calling the shipping action workflow
2. Route item actions to the item-action workflow
3. Re-fetch actions and render their types in the UI

Example fix

// before
await deleteDraftOrderShippingMethodWorkflow(container).run({ input: { order_id, action_id } }) // ITEM_ADD action

// after
if (action.action === "SHIPPING_ADD") {
  await deleteDraftOrderShippingMethodWorkflow(container).run({ input: { order_id, action_id: action.id } })
} else {
  await removeItemDraftOrderWorkflow(container).run({ input: { order_id, action_id: action.id } })
}

if (action.action !== "SHIPPING_ADD") throw new Error("Not a shipping-add action")

const isShippingAddAction = (a: { action: string }) => a.action === "SHIPPING_ADD"

When it happens

Trigger: Passing an ITEM_ADD or other non-SHIPPING_ADD action id to a draft-order shipping method action workflow.

Common situations: Client routes all action removals through the shipping workflow; stale action list where the action type differs from what the UI assumed.
