I have a bot that I have built using the bot framework v4. I am accessing the bot using the MS webchat.
I am trying to send an event activity from the bot to the chat client. I get an error when I make the final call to send using SendToConversationAsync.
The code I am using is identical to how I successfully did this in bot framework v3.
Can someone shed some light on what I might be doing wrong here?
This is the code I use to send the event
internal async Task SendSpecialEvent(Activity activity)
{
Activity clearMessage = activity.CreateReply();
clearMessage.Type = "event";
clearMessage.Value = "executeSpecialEvent";
var connector = new ConnectorClient(new Uri(activity.ServiceUrl));
await connector.Conversations.SendToConversationAsync(clearMessage);
}
The error message is
"Value cannot be null.\r\nParameter name: clientId"
This is the stack trace from the exception. The error has something to do with the appid/password for the bot but I'm not sure why that is. The bot is working perfectly fine up to this point.

OK, I found something that works I've change the code to use ReplyToActivityAsync() instead of using the ConnectorClient. This new code looks like this
Activity clearMessage = stepContext.Context.Activity.CreateReply();
clearMessage.Type = "event";
clearMessage.Value = "executeSpecialEvent";
await stepContext.Context.SendActivityAsync(clearMessage,
cancellationToken);
I would still like to learn why my original code doesn't work with Botframework v4
