How to cancel a line with backordered status of a sales order using Rest API?

Content

I am trying to cancel the line of a sales order that remained in backordered status. But I am trying using the PATCH method of the Rest API '/fscmRestApi/resources/11.13.18.05/salesOrdersForOrderHub/{OrderKey}/child/lines/{FulfillLineId}'

The payload I am using is as follows:

{
  "CancelReasonCode": "CANCELACION DEL CLIENTE",
  "CancelReason": "Cancelación",
  "CanceledFlag": true,
  "OrderedQuantity": 0
}

However, I get the error:

SourceTransactionLineNumber 1, SourceScheduleNumber 1: A closed or canceled line cannot be updated
SourceTransactionLineNumber 1, SourceScheduleNumber 1: The request failed because it doesnt include a value for attribute SourceLotSerialId, or value that it does provide isnt valid.
The request failed because it includes lot serial details on an order line that isnt a return line. Include these details only on a return line.
