GORM version is v1.25.1.

I encountered the same error when I use the Pluck to get single column value. My code as follow:

func GetModelStatus(id uint64) (status constants.ModelStatus, err error) {
    err = Db.Model(&model.Model{}).Where("id = ?", id).Pluck("status", &status).Error
    return
}

The type constants.ModelStatus defined as follow:

type ModelStatus int

Can anyone help me, thx.

I found taht in the low version, such as 1.24.1, the Pluck no problem.

In desperation, I use Scan indtead of Pluck to get single column value and succeeded.
