Random Bug

[cheditx]

To be honest i don't know what really happened, i just got this error after receiving some updates on the bot

System.NullReferenceException: Object reference not set to an instance of an object. at TelegramBotBase.BotBase.Client_MessageLoop(Object sender, UpdateResult e) at TelegramBotBase.Base.MessageClient.OnMessageLoop(UpdateResult update) at TelegramBotBase.Base.MessageClient.HandleUpdateAsync(ITelegramBotClient botClient, Update update, CancellationToken cancellationToken) at Telegram.Bot.Polling.DefaultUpdateHandler.HandleUpdateAsync(ITelegramBotClient botClient, Update update, CancellationToken cancellationToken) at Telegram.Bot.Polling.DefaultUpdateReceiver.ReceiveAsync(IUpdateHandler updateHandler, CancellationToken cancellationToken) at Telegram.Bot.TelegramBotClientExtensions.ReceiveAsync(ITelegramBotClient botClient, IUpdateHandler updateHandler, ReceiverOptions receiverOptions, CancellationToken cancellationToken) at Telegram.Bot.TelegramBotClientExtensions.<>c__DisplayClass127_0.<<StartReceiving>b__0>d.MoveNext()

EDIT:

i ""fixed"" just by switching from the version 6.5 to 6.4

Hey, 6.5 has removed a lot of try/catches so you should debug a bit more into the issue. Do you have an example project to test on ?

Is this the full stack trace ? Cause there havent been changes within the last called method for a long time.

Yes its all the console print, i used a simple example code with FormBase implementation

var bot = BotBaseBuilder.Create().QuickStart<MessagesListener>("XXXXXXXXXXXXXXXXXXXXXXXX").Build(); await bot.Start();

    Console.ReadLine();
    await bot.Stop();
    
  and then a class with MessagesListener : FormBase with Load(MessageResult)

I tested it as well with

And it works as expected. I would say there is probably some issue within your StartForm. But I do not know exactly.

Did you sent a message or /start command to invoke the bot ?

[MajMcCloud]

Did you used a StartFormFactory or just a Form ?

My code worked well all the time, until i added it on a group idk what happened, i used the same FormBase as always and it just returned that error, i tried with another token and it started working again

[MajMcCloud]

Some stuff regards bot commands I groups changed. But I believe that has nothing to do, with your case.

Edit: but that's a good hint, I'll try that out to reproduce it.

Edit2: groups works different, therefore is a special form called "SplitterForm"

Another token means probably different group settings. If you got access to both, please check the BotFather settings for groups. There are different ones.

@cheditx So this issue can be closed ?

@cheditx So this issue can be closed ?

i don't think so, because everytime a bot join a group the bot gets an error...

Then I need more details or an example project. I added my testbot to a group and it works fine. (I used the public available TelegramBotBase.Example project)

So please give more insights on what you do exactly.

Fixed via #67 and version 6.5.1
