错误码400，说是少了个Type，前天添加还正常来着，不明所以 
{
    "data": {},
    "error": [
        {
            "code": "invalid_union",
            "errors": [],
            "note": "No matching discriminator",
            "discriminator": "type",
            "path": [
                "type"
            ],
            "message": "Invalid input"
        }
    ],
    "success": false
}

更绝望的是  我在命令行里添加 找不到自定义模型选项了
