Unsupported relations for schema

I have four nested models (simplified here):

type Client struct {
    gorm.Model
    UUID                   uuid.UUID `gorm:"type:uuid"`
    Activity               Activity 
}

type Activity struct {
    gorm.Model
    ClientID        uint
    LoginActivities []LoginActivity
}

type LoginActivity struct {
    gorm.Model
    ActivityID uint
    UUID       uuid.UUID
    Timestamp  time.Time
    Device     DeviceInfo
}

type DeviceInfo struct {
    gorm.Model
    LoginActivityID uint
    Platform        string
}

And I want to retrieve all nested models with:

database.db.
    Where("uuid = ?", clientID).
    Preload("Activity.LoginActivities.DeviceInfos").
    First(&client). 
    Error

However, I get the error DeviceInfos: unsupported relations for schema LoginActivity

Is the model wrongly set or the query wrong?

You've used Preload("Activity.LoginActivities.DeviceInfos") but the member that represents the relationship in LoginActivity is Device.

You should instead preload with Preload("Activity.LoginActivities.Device")
