BUG: Malformed @ mentions in Message extension payload

[aneesh631]

The original message looks like

test add comment with mentions @Piyush Kumar and @Arka Dutta

When the message extension is invoked the payload looks like:

{
  ...,
  "value": {
    ...,
    "messagePayload": {
      ...,
      "body": {
        "contentType": "html",
        "content": "<p>test add comment with mentions <at id=\"undefined\"></at> <at id=\"undefined\"></at> and <at id=\"undefined\"></at> <at id=\"undefined\"></at><at id=\"undefined\"></at><semantic-object></semantic-object><at id=\"undefined\"></at><semantic-object></semantic-object></p>"
      },
      "mentions": [
        {
          "id": 0,
          "mentionText": "Piyush",
          "mentioned": {
            "device": null,
            "conversation": null,
            "user": {
              "userIdentityType": "aadUser",
              "id": "<piyush_user_id>",
              "displayName": "Piyush"
            },
            "application": null
          }
        },
        {
          "id": 1,
          "mentionText": "Kumar",
          "mentioned": {
            "device": null,
            "conversation": null,
            "user": {
              "userIdentityType": "aadUser",
              "id": "<piyush_user_id>",
              "displayName": "Kumar"
            },
            "application": null
          }
        },
        {
          "id": 2,
          "mentionText": "Arka",
          "mentioned": {
            "device": null,
            "conversation": null,
            "user": {
              "userIdentityType": "aadUser",
              "id": "<arka_user_id>",
              "displayName": "Arka"
            },
            "application": null
          }
        },
        {
          "id": 3,
          "mentionText": "Dutta",
          "mentioned": {
            "device": null,
            "conversation": null,
            "user": {
              "userIdentityType": "aadUser",
              "id": "<arka_user_id>",
              "displayName": "Dutta"
            },
            "application": null
          }
        }
      ]
    }
  }
}

As you can see the mentions are malformed and every username is separated into space separated tokens. When the message is read using the graph api the mentions show up properly, i.e. one mention entry for a single mention. Can you open a bug for this? Thanks.

@aneesh631 - Could you please share repro steps to try at our end?

[Nivedipa-MSFT]

@aneesh631 - How are you creating and generating the messaging extension payload? Can you please share the repro steps or reference doc if any?

[aneesh631]

Steps:

1. Create an Azure bot with a Teams channel switched on, and a teams app that can be installed in a group chat scope. Add a message extension to it.
2. Create a group chat with a couple of users in it. Add the teams app to it.
3. Send a message in the group chat with user mentions.
4. Invoke the message extension on that message.
5. The payload received for this activity has malformed mentions. The payload that I specified in my earlier message highlights what is exactly wrong with it.

@aneesh631 - We are able to repro this issue and we have raised a bug for it. We will let you know once we get updates on it.

@Nivedipa-MSFT The same issue occurs when @mentioning a bot together with other user mentions.

Example: Add a bot to a group chat that has other users @mention the bot together with other users "John Doe" and "Jane Doe" like so:

@bot @Jane Doe @John Doe this is a test

The bot will receive an activity with a total of 5 mentions instead of 3. This used to work fine.

[Nivedipa-MSFT]

@matthiasdilger - We have added this scenario in bug. We will let you know when there is an update on bug.
