The brief
Repair handler.py so every record is attempted once and a record failure does not stop later records. Preserve the supplied process_order import and lambda_handler(event, context) signature. Return exactly one batchItemFailures list containing only failed records, each as an itemIdentifier set to that record's messageId. An empty or fully successful batch must return an empty list, and the incoming event must remain unchanged.
