cannot unmarshal object into Go struct field .last_message of type tdlib.MessageSender

[KaoriEl]

I am using the second version of the library, and when receiving all the user's chats, this error constantly drops, does anyone know how to fix it? json: cannot unmarshal object into Go struct field .last_message of type tdlib.MessageSender

func getChatList(client *client.Client, limit int) ([]*tdlib.Chat, error) {

var allChats []*tdlib.Chat

var chatList = tdlib.NewChatListMain()

var chats, getChatsErr = client.GetChats(chatList, int32(limit))
if getChatsErr != nil {
    return nil, getChatsErr
}

for len(chats.ChatIDs) > limit {
    // get chats (ids) from tdlib
    _, err := client.LoadChats(chatList, int32(limit-len(chats.ChatIDs)))
    if err != nil {
        if err.(tdlib.RequestError).Code != 404 {
            chats, err = client.GetChats(chatList, int32(limit))
            break
        }
        return nil, err
    }

    chats, err = client.GetChats(chatList, int32(limit))
}

if len(chats.ChatIDs) == 0 {
    return allChats, nil
}

for _, chatID := range chats.ChatIDs {
    // get chat info from tdlib
    var chat, getChatErr = client.GetChat(chatID)
    if getChatErr == nil {
        allChats = append(allChats, chat)
    } else {
        return nil, getChatErr
    }
}

return allChats, nil

}
