Error: ✗ contact points: could not find an Alertmanager configuration

I am trying to provision the contact points. This is my yaml file

apiVersion: 1
contactPoints:

  • orgId: 1
    name: sdi
    receivers:
    • uid: c5d9104c-23bb-4fb3-8058-0ab15965821b
      type: email
      settings:
      addresses: abc@gmail.com
      singleEmail: true
      subject: Infrastructure issue
  • orgId: 2
    name: vs_health
    receivers:
    • uid: __Yz1_j4z
      type: email
      settings:
      addresses: abc@gmail.com
      singleEmail: true
      subject: ‘{{ template “hc.subject” . }}’

It gives me error Error: ✗ contact points: could not find an Alertmanager configuration

I have added email and settings in this yaml. What I am doing wrong here?
