Gorm Find with interface does not work

Your Question

When using Find with a value which is of type any or interface{}, the slice does not get filled with the result. See example below.

type MyModel struct {
    ID   int64 `gorm:"primaryKey"`
    Name string
}

// This works
func fetchAll() ([]MyModel, error) {
    var result []MyModel
    if err := db.Find(&result).Error; err != nil {
        return nil, err
    }
    return result, nil
}

// This does not work
func fetchAll() ([]MyModel, error) {
    var result any
    result = []MyModel{}
    if err := db.Find(&result).Error; err != nil {
        return nil, err
    }
    return result, nil
}

There are no errors and no indication what is going wrong. My real use case is a bit more complicated, but this the minimal reproducable example.

The document you expected this should be explained

https://gorm.io/docs/query.html

Expected answer

Either an error or that it fills the slice as expected.
