AWS::SSM::Association issue

[lloydpick]

On the AWS::SSM::Association object it has a property called Parameters, when trying to specify that in cfer like this...

resource :OperationsSsmPatchBaselineAssociation, "AWS::SSM::Association" do
  association_name "ops-patch-association"
  name "AWS-RunPatchBaseline"
  schedule_expression "cron(0/30 * * * ? *)"
  parameters do
    operation ["Scan"]
  end
  targets [
    {
      "Key": "tag:Inspector",
      "Values": ["true"]
    }
  ]
end

It just silently drops the Parameters section (probably because of it's unfortunate name)...

{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Description": "",
  "Metadata": {
    "Cfer": {
      "Version": {
        "major": 0,
        "minor": 6,
        "patch": 0
      }
    }
  },
  "Parameters": { },
  "Mappings": { },
  "Conditions": { },
  "Resources": {
    "OperationsSsmPatchBaselineAssociation": {
      "Type": "AWS::SSM::Association",
      "Properties": {
        "AssociationName": "ops-patch-association",
        "Name": "AWS-RunPatchBaseline",
        "ScheduleExpression": "cron(0/30 * * * ? *)",
        "Targets": [
          {
            "Key": "tag:Inspector",
            "Values": [
              "true"
            ]
          }
        ]
      }
    }
  },
  "Outputs": { }
}

The work around we found was to do...

resource :OperationsSsmPatchBaselineAssociation, "AWS::SSM::Association" do
  association_name "ops-patch-association"
  name "AWS-RunPatchBaseline"
  schedule_expression "cron(0/30 * * * ? *)"
  self["Properties"]["Parameters"] = { "Operation": ["Scan"] }
  targets [
    {
      "Key": "tag:Inspector",
      "Values": ["true"]
    }
  ]
end
