Hello.  We have an Azure Logic App that gets Ship Confirmations from our WMS and updates Shopify through the Admin/Fulfillment API.  It was working for months with no errors and then recently, three orders failed.   I see nothing wrong with the data being sent.  The information for the last order is below.  I was able to fulfill the first two orders through the online Shopify Store pages and add the tracking information.  I haven't done that. yet, for the order below. 

Can someone look at why this call is failing for this order?

Hello I had one more order like this happen again.  One thing common, is when I view these from the Shopify Store, I see the line items in two separate groups.  One group will have line items marked as subscription and the group don't have any items marked as subscription.  I believe when an order is one or the other everything works, but when it has both it fails.  Can someone from Shopify please look into it?
