[BUG] Can't send messages to the Power Automate flow

[savissimo]

Describe the bug I followed instructions and installed the receiver in my OpenShift cluster. However, I got no messages in Teams (yes, there are alerts firing). I find a stream of these logs in my pod:

Version Docker image v.1.5.2

To Reproduce I followed the instructions from here: https://examples.openshift.pub/cluster-configuration/monitoring/alertmanager/microsoft-teams-receiver/

Expected behavior The Power Automate flow accepts the request and posts the message.

I resolved this with the following:

+++ b/pkg/service/service.go @@ -83,6 +83,8 @@ func (s simpleService) post(ctx context.Context, c card.Office365ConnectorCard, return pr, err }

•   req.Header.Set("Content-Type", "application/json")
  

•   resp, err := s.client.Do(req)
    if err != nil {
            err = fmt.Errorf("http client failed: %w", err)

Great news, thank you! Will there be a Docker release for this fix?

Just for info: Microsoft is retiring the Office 365 connectors soon. Official announcement: https://devblogs.microsoft.com/microsoft365dev/retirement-of-office-365-connectors-within-microsoft-teams/

This bugfix is needed to switch to the Power Automate workflows.

MS Teams has started to add the following text when you use the old API:

Action Required:
O365 connectors within Teams will be deprecated and notifications from this service will stop.

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.

In fact I used the service in conjunction with a Power Automate flow. This may be the reason for the bug.

Great news, thank you! Will there be a Docker release for this fix?

I would imagine once the PR is merged you will be able to build the docker image with: make docker

[savissimo]

Should I push that image to a private repository of mine or will it be pushed to the project's repository on quay.io?

Hi :) Has anyone been able to use Power Automate flows after changing the line of code to send as application/json ?

So far here, I keep getting errors because the format expected by Power Automate is different (seems they only support Adaptive Cards being sent through webhooks ?)

FWIW, here are some additional references that you may find useful:

• https://gist.github.com/chusiang/895f6406fbf9285c58ad0a3ace13d025
  • lots of discussion & an example script to use adaptive cards format
• https://github.com/tlolkema/simple-teams-message
  • the action.yml file contains an example payload that could be adapted for use here

thanks for providing this msteams proxy. it pretty did his job until now. but with the power automate change it would be nice to have the ContentType Header fixed or configureable.

So thanks for fixing this :)

I believe an MS Teams integration was added directly into Alert Manager supporting Flows (not tested yet on my side)

That's true, but some users reported that the new integration offers much less flexibility than this service. It would be great to be able to choose what to use.
