Teams Webhook for SolarWinds Alerts

I added this JSON in the workflow steps on Teams and it worked:

{
"type": "TextBlock",
"text": "[Acknowledge Alerts](">https://URL)"
}

Hello,
I am trying to get this working and have limited knowledge on how to set this up.

I created an alert to post but get an error message saying:

Solarwinds

Teams workflow error:
The execution of template action 'Send_each_adaptive_card' failed: the result of the evaluation of 'foreach' expression '@triggerOutputs()?['body']?['attachments']' is of type 'Null'. The result must be a valid array.

This is the body in SolarWinds alert:

{
  "title": "ALERT TRIGGER: ${N=SwisEntity;M=Caption} is currently ${N=SwisEntity;M=Status}",
  "text": "DEVICE: [${N=SwisEntity;M=Caption}](${N=SwisEntity;M=DetailsUrl})
  IP ADDRESS: ${N=SwisEntity;M=IP_Address}
  VENDOR: ${N=SwisEntity;M=Vendor}
  MODEL: ${N=SwisEntity;M=MachineType}
  [ALERT DETAILS](${N=Alerting;M=AlertDetailsUrl})
  [ACKNOWLEDGE THIS ALERT](${N=Alerting;M=AcknowledgeLink})"
}

Below is a screenshot of the action in solarwinds and of the teams workfolw.

I am thinking something is missing on the teams side to maybe format the adaptive message.

I used these instructions and got it working if someone else has problems.
