/**
 * When rating a Shipment or Pickup, some carriers may fail to generate rates.
 * These failures are returned as part of the Shipment or Pickup as part of their messages attribute, and follow a common object structure.
 *
 * It is important to note that the message value for any member of this list comes directly from the carrier, not from EasyPost.
 * This means that if you see an authentication or other non-shipping error here, it is not an issue between you and EasyPost, it is an issue between you and the carrier, or an issue with the given data.
 *
 * @see https://docs.easypost.com/docs/shipments/messages#message-object
