How to use Update Activity and Delete Activity actions

Describe the bug

I’m trying to use the Update Activity action to update an activity send before. The action accepts an Activity Id, but it’s not clear where to get the Activity Id from. The watermark suggests =dialog.lastActivityId but that property never gets polulated.

Version

1.1.1

OS

• macOS
• Windows
• Ubuntu

To Reproduce

Steps to reproduce the behavior:

1. Create an empty bot with an unknown intent trigger
2. Add a Response action
3. Add an Update Activity action and set Activity Id to =dialog.lastActivityId
4. Run in the emulator and type something
5. See the error 'activityId' cannot be null.

Ok, I am able to get the activity ID. But I am unable to get any activity to update.

First of all, there are only some channels that allow you to update the activity. From some poking around, it should be: Teams, Slack, Telegram, and Skype.

This contradicts what is currently listed here.

So, it should at least work in Teams. I have been able to retrive the last activity ID in the following channels: Emulator, Web Chat, Teams, Telegram and Skype.

It looks like it won’t work or be supported in Emulator or Web Chat. At least for now.

Here is my LG:

# SendActivity_003038()
- You said '${turn.activity.text}'

# SendActivity_CuRkhr()
- The last "you said" activity was ${turn.lastresult.id}

# UpdateActivity_Activity_VvGbJB()
[Activity
    Text = Should be new text
]

And here is my dialog:

{
  "$kind": "Microsoft.OnUnknownIntent",
  "$designer": {
	"id": "821845"
  },
  "actions": [
	{
	  "$kind": "Microsoft.SendActivity",
	  "$designer": {
		"id": "003038"
	  },
	  "activity": "${SendActivity_003038()}"
	},
	{
	  "$kind": "Microsoft.SendActivity",
	  "$designer": {
		"id": "CuRkhr"
	  },
	  "activity": "${SendActivity_CuRkhr()}"
	},
	{
	  "$kind": "Microsoft.UpdateActivity",
	  "$designer": {
		"id": "VvGbJB"
	  },
	  "activityId": "turn.lastresult.id",
	  "activity": "${UpdateActivity_Activity_VvGbJB()}"
	}
  ]
}

@benbrown Any other pointers or things I may be missing to get the activity to actually update once I have the activity ID?

Sure, this feature is not yet mature and I have reverted to re-do my bot in C#.
