Gorm when the data is empty, json parsing fails ！！

type AppLoginLog struct {
    Id            uint                `gorm:"column:id;" json:"id"`
    JsonInfo      JSONInfo `gorm:"column:json_info" json:"json_info"`
}

type JSONInfo struct {
    Aid         string `json:"aid"`
    Check       bool   `json:"check"`
    UUID        string `json:"uuid"`
}

func (j *JSONInfo) Value() (driver.Value, error) {
    b, err := encoding.GetCodec("json").Marshal(j)
    return string(b), err
}

func (j *JSONInfo) Scan(v interface{}) error {
    return encoding.GetCodec("json").Unmarshal(v.([]byte), j)
}

when the data is empty, return errors gorm.ErrRecordNotFound , but return error is sql: Scan error on column index 16, name \"json_info\": json: cannot unmarshal string into Go struct field JSONInfo.mcc of type int

我的英文不太好，我用汉语在表述一下：

我的查询数据的时候存在了数据为空的情况，正常应该返回 gorm.ErrRecordNotFound， 但是由于我嵌入了一个JSONInfo结构体，本意是希望他能够将json给解析，就报了错，错误为：sql: Scan error on column index 16, name \"json_info\": json: cannot unmarshal string into Go struct field JSONInfo.mcc of type int 但是这种错误不应该是 gorm.ErrRecordNotFound 么，我应该怎么使用它？

感谢大佬 ~
