Gorm Multiple Records Query:index out of range [0] with length 0

Your Question

So I have a model,below:

type Conversation struct {
    ConversationId string `gorm:"primaryKey"`
    StartTime      *time.Time
    EndTime        *time.Time
    Title          string
    Status         string // Created、Activate、Idle、Expired、Abandoned、Renewed、Terminated、Invalidated、Migrated
    CreatedBy      string
    LastActive     *time.Time
    MessageCount   int
    Language       string
    TokensConsumed int64
}

I create 2 records and it success. But i try query this 2 like a user created 2 conversation in my context got an err:

func (rd *ResourceDao) GetConversationsByUserId(userId string) ([]model.Conversation, error) {
    var cs []model.Conversation
    err := rd.DB.Model(&model.Conversation{}).
        Where("created_by = ?", userId).
        Find(&cs).Error
    return cs, err
}

err info

[29.284ms] [rows:2] SELECT * FROM `conversation` WHERE created_by = 'user-4fbfe0c2-f035-11ee-98b4-9ae0cc7dbf08'
