I have built an application where i'm accessing the copilot studio bot through Direct Line authentication. I'm also using Botframework.

In the Copilot Studio page I have configured a welcome message, which shows up in the example bot. My problem arrises when I open that bot in the application. The welcome message does not show up.

Anyone that has an idea of what might cause this, and even a possible fix?

Hi @JL-04070750-0

Sorry for your troubles.

So I do not know what you mean in an App, sorry I mean it as in what type of App.

What I can say is that in many cases (I won't say all), depending on where it is embedded, it will not trigger your initial Topic (default), because it doesn't see that a Conversation has actually "Started" and so therefor it won't do anything until someone types in it. That is standard behavior and is what it sounds like you are facing.

I DO realize that in the Test environment it works, I would bet if you published to the Demo Website it would work (so please try that and let me know) , but in an app... even in Teams, many times they will not.

Is that silly... yeah.. but is what I believe is happening to you, especially if you publish to the Demo Website and it works.

I do not know of any hacks to force it to do it either, I am sure there are.. well maybe, but none I can safely recommend if I am correct in my statements and reason.

While not what you want, if this answers your question please mark as such and maybe a like.

But feel free to come back with more details as I am curious if it works in the Demo Site

@Michael E. Gernaey Because I have integrated this in my system with Direct Line, the demo website won't show anything because of the missing token (I believe). I am testing some solution with the botframework-webchat package called postActivity:

directLine.connectionStatus$.subscribe((connectionStatus: ConnectionStatus) => { if (connectionStatus === ConnectionStatus.Online && !welcomeEventSent) { welcomeEventSent = true; directLine.postActivity({ type: 'event', name: 'webchat/join', value: { locale: this.localeId, timestamp: new Date().toISOString() }, } as Activity); } });

though no luck..

I found this stackoverflow post about backchannels to trigger events after you connect to the chat: https://stackoverflow.com/questions/56111293/botframework-how-to-fixwelcome-message-is-not-getting-displayed-to-the-user

Do you know if this might be a viable solution?

EDIT:

I have found a solution to this that works. Though it will not be the "true" welcome message, it will be a second, separate topic that is triggered.

All I needed to do was to add the parameter "from: { id: "someId" } to postActivity, and then in my renderWebchat I pass the same id. As a topic I added a custom client event that listens to the event "webchat/join", and then sends the welcome message. I of course also needed to ass .subscribe() to the postActivity method.
