Botframework-sdk: [Telegram] Proactive bot in C# would not work in Telegram

[isaacy]

Repro:

1. Create a proactive bot in c#.
2. Register the bot with Telegram.
3. in Telegram, add the bot, and send a message.

Expected:
The bot will be able to receive the queued message.

Actual
The bot was not able to recevied the queued message.
in the bot log, here is the error:

2017-01-07T06:42:01.536 Function completed (Failure, Id=e680d066-9132-4e63-89bd-61badd49fbe1)
2017-01-07T06:42:01.552 Exception while executing function: Functions.messages. Microsoft.Bot.Connector: Unknown bot .

This does not repro in proactive bot for JS though.

@msft-shahins Any idea why this would fail for a bot developed in C#, but succeed with a Node.JS bot?

[jameslew]

@maxpert , any ideas?

[macrobug]

So far I have identified this is the line where the error occurs:

await client.Conversations.ReplyToActivityAsync(triggerReply);

That is inside:

case ActivityTypes.Trigger:

In the file run.csx

Seems like the ResumptionCookie is wrong or something along those lines.

This is fixed now?

[eanders-MS]

We've tracked down the issue, and a fix is in progress. Thanks for your patience.

[macrobug]

Thanks @eanders-MS , Would you let us know when this fix is deployed to the portal?

[kkarahainko]

@eanders-MS any updates?

[SkyQuant]

Should I already start to write native Telegram bot or update with fixed proactive messaging problem is coming?

[eanders-MS]

Apologies for the slow response here. A fix for this issue is still planned, but at the moment I cannot provide a timeline for when it will be done.

@isaacy Are you still experiencing the issue after upgrading to BotBuilder 3.8.1?

@kkarahainko Are you still experiencing the issue after upgrading to BotBuilder 3.8.1?

The issue persist in 3.8.1, anyone can help me to workaround?

[eanders-MS]

A user posted a workaround here: https://github.com/Microsoft/BotBuilder/issues/2347

This error occurs if you only specify the Id "new ChannelAccount (botId)" If you add the name "new ChannelAccount (botId, botName)", everything will work

I had the same issue with Telegram, using version 3.15.3.
The workaround with creating ChannelAccount(botId,BotName) instead of only ChannelAccount(botId) not worked. The error "The bot referenced by the 'from' field is unrecognized"
The issue/bug still exists?
