Thanks.  I've tried this... dropping the line items or the location_id doesn't seem to change anything.  Any other ideas? could it be a setting issue on the fulfillment service?  or on the "InventoryItem"? inventory_item = shopify.InventoryItem.find(...

I'm using the python sdk  ShopifyAPI==12.2.0 and api version "2023-01."Whenever i try to save my fulfillment I get the errorCannot create fulfillment for the fulfillment order In [50]: fulfillment.to_dict(){'location_id': xxx,'notify_customer': False...
