Why is the shippingLine null in my draftOrder on a mobile app?

[brunomoonly]

Hi,

We have a mobile app that uses the shopify admin api. We use draftOrderCalculate to get available shipping rates. After that we try to create a draftOrder with the selected shipping line but the createDraftOrder mutation returns ready is false and shippingLine is null.

{
  id: 'gid://shopify/DraftOrder/x',
  name: '',
  ready: false,
  shippingLine: null
}

Does anyone know why?

Thanks!

Hi, did you find a fix for this? And out of interest, do you have any shipping options set under “carrier and app rates” in the shopify dashboard? We found that this issue is associated with those rates somehow.
