MS Teams Bot sign-in not working, says "This action can't be performed since the app does not exist or has been uninstalled."

Question

I am creating a simple MS Teams messaging bot that requires auth/sign-in.

I am using https://smba.trafficmanager.net/amer/v3/conversations/{conversationId}/activities to send a non-reply bot message to user that includes a hero card with a sign-in button.

The body looks somewhat like this:

{
"type": "message",
"from": {
    "id": "abc",
    "name": "messaging-bot"
},
"conversation": {
    "id": "789",
    "name": "test",
    "tenantId": "456",
    "role": "bot",
    "conversationType": "personal"
},
"recipient": {
    "id": "123",
    "name": "test"
},
"attachments": [
    {
        "contentType": "application/vnd.microsoft.card.hero",
        "content": {
            "title": "title goes here",
            "subtitle": "subtitle goes here",
            "text": "descriptive text goes here",
            "buttons": [
                {
                    "type": "signin",
                    "title": "Click me to sign in",
                    "value": "<my-signin-url>"
                }
            ]
        }
    }
]

}

When user receives hero card and clicks sign in button, user gets the following error:

This action can't be performed since the app does not exist or has been uninstalled.

I have added my sign-in domain to valid domains, and uploaded app package to MS Teams, so not sure why I am getting this error.

The app is created through Developer Portal in Ms Teams. For now, we are just creating a simple messaging app that relies on the bot messaging endpoint

May someone help with this?

Answer 1

If you are using Microsoft AD, Please add below in valid domain section of your app manifest:

token.botframework.com
login.microsoftonline.com

Quick update on answer. I found that installing/uninstalling app when sideloading app is a bit buggy. Things worked after I closed my MS Teams client and re-opened it
