I am trying install custom bot on teams by AppStudio, but ambiguous error occurs on the bottom:

When I try to install bot

Manifest which I use to install bot:

    "$schema": "https://developer.microsoft.com/en-us/json-schemas/teams/v1.3/MicrosoftTeams.schema.json",
    "manifestVersion": "1.3",
    "version": "1.0.0",
    "id": "9bf3b749-ec5a-4cf2-94df-794a9898cc94",
    "packageName": "com.contoso.helloworld",
    "developer": {
        "name": "Contoso",
        "websiteUrl": "https://www.microsoft.com",
        "privacyUrl": "https://www.microsoft.com/privacy",
        "termsOfUseUrl": "https://www.microsoft.com/termsofuse"
    "icons": {
        "color": "color.png",
        "outline": "outline.png"
    "name": {
        "short": "Hello World",
        "full": "Hello World App"
    "description": {
        "short": "Hello World App",
        "full": "This sample app provides a very simple app for Microsoft Teams. You can extend this to add more content and capabilities."
    "accentColor": "#60A18E",
    "bots": [
            "botId": "12d10a40-4886-4c55-a968-5898a4106c63",
            "scopes": [
            "supportsFiles": false,
            "isNotificationOnly": false
    "permissions": [
    "validDomains": []

As bot to test I use project from this repo.

Do you have idea how solve this problem or is place in AppStudio where I can find logs or description what cause this problem?

Ps. Also I found some links to similar issue on github. Is it possible that my tenant not allow app sideloading?
