Transform a Transfer Order to generate an Item Fulfillment Event Hello everyone, I am currently trying to create a Transfer Order in NS through integration call, but when I try to submit the information to trigger the "Item Fulfillment" I am facing below error:

"Error while accessing a resource. You have attempted an invalid sublist or line item operation. You are either trying to access a field on a non-existent line or you are trying to add or remove lines from a static sublist."

I am currently using SuiteTalk REST API.

{
  "item": {
    "items": [
      {
        "itemreceive": true,
        "orderLine": 1,
        "quantity": 1
      }
    ]
  },
  "externalid": "test123"
}

however, if I change the orderline to "2", it generates the Item Fulfillment correctly, I already looked up in the original item (line:1), but there's nothing related to that id. the way I figured out that, was using the UI and then making a call to retrieve the Item Fulfillment and see what was different. any suggestion? I am a bit lost on this as our Transfer order has multiple lines

TO's are weird.

Noted, thanks for the inputs
