Fulfillment API request returning error "The required line_items_by_fulfillment_order field is missi

[aperkins]

Trying to create a fulfillment by line item in postman, which worked previously, but is now returning the error 

"The required line_items_by_fulfillment_order field is missing."

Here is the code:  

{

                "fulfillment": {

                                "message": "The package was shipped this morning.",

                                "notify_customer": "true",

                                "tracking_info": {

                                                "number": "9241990361700120347077",

                                                "url": "https://tools.usps.com/go/TrackConfirmAction_input",

                                                "company": "USPS",

                                                "line_items_by_fulfillment_order": [

                                                                {

                                                                                "fulfillment_order_id": "6058467131647",

                                                                                        "shop_id": "62443585791",

                                                                                "fulfillment_order_line_items": [

                                                                                                {

                                                                                                                "id": "12878144831743",

                                                                                                                "quantity": "1"

                                                                                                }

                                                                                ]

                                                                }

                                                ]

                                }

                }

}

Any help would be greatly appreciated!

Update: I removed the shop_id after realizing that isn't part of the scope. Still getting the error though.

I figured out the problem. line_items_by_fulfillment_order was incorrectly nested in tracking_info.
