Why Binance API uses different structure for successful or failed requests?

Am I lacking something or is it the default behaviour where AllOrders API returns an array of transactions on the root degree when successful; nevertheless on failure it returns a single object with error message. It will have been approach easier to make use of the API if a single structure supported both - for instance:

"code": "ERROR_CODE",
"msg": "ERROR_MESSAGE"
"status": "SUCEESS/ ERROR"

"assets":
[ , ]

Due to two totally different buildings, its making it really arduous to handle the success or error knowledge buildings.
