Question

I am trying to publish a MS Teams Chat bot on App Source but have came across the following error

Here is how my manifest.json file looks like

{
  "$schema": "https://developer.microsoft.com/en-us/json-schemas/teams/v1.5/MicrosoftTeams.schema.json",
  "manifestVersion": "1.5",

  },
  "accentColor": "#F9F9FA",

          "commands": [

              "title": "help",
              "description": "Provides you the list of commands that you can enter"
            },
            {
              "title": "cancel",
              "description": "Cancels the current operation"
            }
          ]
        },
        {
          "scopes": [ "personal", "groupchat" ],
          "commands": [
            {
              "title": "main menu",
              "description": "This command takes you to the main menu"
            },
            {
              "title": "help",
              "description": "Provides you the list of commands that you can enter"
            }
          ]
        }
      ]
    }
  ],
  "permissions": [
    "identity",
    "messageTeamMembers"
  ],
  "validDomains": [
    "token.botframework.com"
  ]
}

The validator gives the following error as well

I have looked into Stackoverflow for this message as well as searched online but I am not able to get an exact article on how to fix this issue. I read about how the app has to work for all types of devices but the manifest.json file doesnt show how that is to be done. Can someone forward me a template that I can build my manifest.json file on? Or am I doing something wrong altogether?

Thank you.

This file resolved the issue. We used AppStudio to get this file.

"IsNotificationOnly"property is added twice in the manifest. Can you please try deleting it and check again.

Assuming that you already have two files "icon-color.png" and "icon-outline.png" along with the manifest.json in the app package zip file. Can you please verify if all three files are added to a zip files and no folder is created inside the zip package.

Can someone forward me a template that I can build my manifest.json file on?

You can maybe start with this one (specifically for search extension), but you'll obviously want to change/trim/add it to do what you are actually wanting to do. https://github.com/microsoft/BotBuilder-Samples/blob/master/samples/csharp_dotnetcore/50.teams-messaging-extensions-search/TeamsAppManifest/manifest.json

More samples have other examples of manifest files.

Additionally, you may want to try and create a manifest from App Studio (MS Teams app that allows you to create them).

Thanks Dana, this recommendation helped. >> **Additionally, you may want to try and create a manifest from App Studio (MS Teams app that allows you to create them)**. — Sash Sheen, Jun 18 '20 at 06:54
