400 BAD Request

Members the 400 bad request response without descriptions is unprofessional. if the request body is wrong then an appropriate response code should be returned by the api endpoint. this makes it easier for software developers to guide themselves. for 7 years av been on this API and i still wonder why nothing has changed. Eg when creating an invoice am glad this {
    "message": "Currency not supported.",
    "code": "INVALID_CURRENCY"
} comes but then beyond that its BAD request without any meaningful response code
