Teams Workflow - Post to a channel when a webhook request is received is'nt working

[alexteo]

Hi with the recent news that 
"Action Required: O365 connectors within Teams will be deprecated and notifications from this service will stop.Learn more about the timing and how the Workflows app provides a more flexible and secure experience. If you want to continue receiving these types of messages, you can use a workflow to post messages from a webhook request. Set up Workflow"

I was then trying to set up workflow as an alternative, it seems easy at first since Microsoft already has an inbuilt workflow just for webhooks.

 
However i keep facing the same problem that results in the flow to fail, this is the error i keep recieving

Its so weird that such a simple flow has problems running, and further more this is suppoedly the new solution so i dont know whats wrong, really seeking all helps and advice, thanks!!

[alexteo]

So i realized the problem is that: attachment is null when it shouldnt in order for the flow to work,

However looking at the output there isn't a 'attachment' parameter in the first place... Any experts able to help with this issue? Thanks in advance 

  

[alexteo]

Someone please help why is my Attachment always null T_T

[Pete7]

Same issue here. They are forcing us to use something in a month where there is no documentation, and it doesn't work.

[alexteo]

Im so glad im not alone in this, for a moment i thought i was struggling with this by myself :,)

[Pete7]

I got it to work by sending a POST using json formatted this way:

{
"type":"message",
"attachments":[
{
"contentType":"application/vnd.microsoft.card.adaptive",
"contentUrl":null,
"content":{
"$schema":"http://adaptivecards.io/schemas/adaptive-card.json",
"type":"AdaptiveCard",
"version":"1.2",
"body":[
{
"type": "TextBlock",
"text": "Sample Text!"
}
]
}
}
]
}

The only other issue is the post is always from the user that created the flow...

[alexteo]

Im so sorry as im new to Power Automate, is it okay if you can send a picture as it'll help me understand better, thanks!!

And also Im currently using Webhook with Gitlab so any new issues in Gitlab posts as notification adaptor cards in the Teams channel, not sure if the problem is only in Gitlab or other platforms for webhook - just FYI

I tried @Pete7 JSON, but I'm getting the same error: "The execution of template action 'Send_each_adaptive_card' failed: the result of the evaluation of 'foreach' expression '@triggerBody()?['body']?['attachments']' is of type 'Null'. The result must be a valid array."

I'm in the same boat, using webhooks for deployment notification from Azure DevOps and Octopus.

I got a sample working:

On the input for the adaptive card json

I put this (example from PA docs):

{
  "type": "OpenApiConnection",
  "inputs": {
    "parameters": {
      "poster": "Flow bot",
      "location": "Channel",
      "body/recipient/groupId": "REDACTED",
      "body/recipient/channelId": "REDACTED",
      "body/messageBody": "@{item()?['content']}\n\n\n\n"
    },
    "host": {
      "apiId": "/providers/Microsoft.PowerApps/apis/shared_teams",
      "connection": "shared_teams",
      "operationId": "PostCardToConversation"
    }
  },
  "runAfter": {
    "Post_card_in_a_chat_or_channel": [
      "SUCCEEDED"
    ]
  }
}

The to test, Postman patload as the following:

{
    "type": "message",
    "attachments": [
        {
            "contentType": "application/vnd.microsoft.card.adaptive",
            "contentUrl": null,
            "content": {
                "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
                "type": "AdaptiveCard",
                "version": "1.2",
                "body": [
                    {
                        "type": "TextBlock",
                        "text": "Hello Darkness my old friend....."
                    }
                ]
            }
        }
    ]
}

However, I am struggerling with more adaptive Postman payloads.

[alexteo]

thanks alot @gavinc - i will try out your solution and see if its fixed for mine

Just chiming in with the same issue here. I can see that the step template script in Octopus can be edited, but I am no where near confident enough in my scripting to start messing with it. I'm hoping Octopus Support have some insights here, but it looks like the webhook from Workflows is definitely not functioning the same way that the O365 connectors do.

[gavinc]

@Doriima 
iirc the template for webhook in Octopus is a cumminty provided one.
Not sure how much support Octopus would actually give on tha 😥

[Doriima]

@gavinc 

Good news! Octopus are actively working on updating that template, though they don't have an ETA. They noticed that someone has created a GitHub issue in their library repository, which they say their developers will update when the fix is ready. I've subscribed to it, and will update here when there's more news.
Here's the link if anyone else wants to check it out: https://github.com/OctopusDeploy/Library/issues/1530

@Doriima 
That's amazing!!!!
Didnt think would touch it.

[alexteo]

this is awesome, thanks @Doriima i guess that would be the solution for this case then xD

I posted similar issue elsewere but no reply so wil try here

Responding to the recent messages in our Teams connectors: "O365 connectors within Teams will be deprecated" we are trymg to use a simple Workflow template:

Post to a channel when a webhook request is received

We add the Team then the channel and try  a test run but get the "Flow xx cannot be installed" error

Tried in Teams Workflows itself and also in Power Automate - which does register it back in Teams but still no joy

Also there are no "Associated apps and flows" in the workflow card  - is this required?

Can anyone help?

[gavinc]

@Doriima I have a call scheduled with my account manager at Octopus on the 15th so will bring this up and try to esculate 

[a-martinez]

Stepping back a bit, using the template I explained above, selecting a valid Team/Channel I get this setup - should a "Run" work?

[gavinc]

@a-martinez 
Yes.
I used Postman to payload test.

Test with this payload:

{
    "type": "message",
    "attachments": [
        {
            "contentType": "application/vnd.microsoft.card.adaptive",
            "contentUrl": null,
            "content": {
                "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
                "type": "AdaptiveCard",
                "version": "1.2",
                "body": [
                    {
                        "type": "TextBlock",
                        "text": "Hello Darkness my old friend....."
                    }
                ]
            }
        }
    ]
}
