Missing notifications when using the Teams sink

[crileroro]

Describe the bug
I am using label filtering in a Teams sink. I've noticed that if I create a list of labels in the include attribute, where the labels name are the same, just the first label value is taken and the second is ignored.

To Reproduce
On Prometheus, I have a metric containing a label workflow_name. Let's call that one workflow_count{workflow_name}. This is used on an alert called workflowFailure. Having these elements, I have defined the following customPlaybook:

 - name: "custom_playbook"
    triggers:
      - on_prometheus_alert:
          alert_name: workflowFailure
    actions:
      - create_finding:
          title: 'test $label.alertname'
          aggregation_key: workflowFailure
          severity: MEDIUM
          description: |
            This is a test of severity Medium

This is the scope section I am using in the Teams sink:

sinksConfig:
  - ms_teams_sink:
      name: ms_teams
      webhook_url: my_url
      scope:
        include:
          - labels:
              - "workflow_name=monitoring-wf-1"
              - "workflow_name=monitoring-wf-2"

If my understanding is correct, the sink will be used when the workflow_name label is either monitoring-wf-1 OR monitoring-wf-2. If the cluster fires 2 alerts, one for monitoring-wf-1 and one for monitoring-wf-2, I would expect to get two different notifications, one for each workflow. However, I only get notified for monitoring-wf-1. If I switch the order of the labels as follows, I get notified for monitoring-wf-2 only instead. My feeling is that if the label key is duplicated (e.g, workflow_name), Robusta will take the first one it finds:

      scope:
        include:
          - labels:
              - "workflow_name=monitoring-wf-2"
              - "workflow_name=monitoring-wf-1"

Expected behavior
I should receive two different notifications.

Hi @crileroro
This wont solve your issue but can you try:

scope:
        include:
          - labels:
              - "workflow_name=monitoring-wf-2"
          - labels:
              - "workflow_name=monitoring-wf-1"

From the docs it looks like your configuration might be checking for label workflow_name=monitoring-wf-2 AND workflow_name=monitoring-wf-1 so in the past you only would have received alerts if both labels exist in your config
