So i'm trying to create a SSM document with the instance ID below, so i can then link it to event bridge to trigger a powershell script based on a cloud watch alarm. I have selected Target type: /AWS::EC2::instance and then the YAML below. But it isn't letting me create the document?

---
schemaVersion: "2.2"
description: "Command Document Example JSON Template"
InstanceId: "i-0bbec63d8fee3d6e3"
description: "Instance ID"
mainSteps:
- action: "aws:runPowerShellScript"
  name: "RunCommands"
  inputs:
    runCommand:
      - "Restart-Service -Name ColdFusion 2018 Application Server"

Trying to create a SSM document, which will target this specific instance, based on this instance ID

It is not a valid SSM document file.

I believe that bellow example should help.

schemaVersion: "2.2"
description: "Example document"
parameters:
  Message:
    type: "String"
    description: "Example parameter"
    default: "Hello World"
mainSteps:
  - action: "aws:runPowerShellScript"
    name: "example"
    inputs:
      timeoutSeconds: '60'
      runCommand:
      - "Write-Output {{Message}}"
