Unable to set scheduler property with sensuctl

[treydock]

Expected Behavior

I'd expect the new Check property of scheduler to be something I can set with sensuctl.

Current Behavior

resource 0: json: unknown field "scheduler"
Error: in /tmp/test: some resources couldn't be parsed

Possible Solution

Steps to Reproduce (for bugs)

[root@sensu-backend /]# cat /tmp/test 
{
  "type": "CheckConfig",
  "api_version": "core/v2",
  "metadata": {
    "name": "test",
    "namespace": "default",
    "labels": {
      "foo": "baz"
    }
  },
  "spec": {
    "command": "check-http.rb",
    "subscriptions": [
      "demo"
    ],
    "interval": 60,
    "publish": true,
    "stdin": false,
    "scheduler": "memory",
    "output_metric_format": "nagios_perfdata",
    "output_metric_tags": [
      {
        "name": "instance",
        "value": "{{ .name }}"
      }
    ]
  }
}

[root@sensu-backend /]# sensuctl create -f /tmp/test 
resource 0: json: unknown field "scheduler"
Error: in /tmp/test: some resources couldn't be parsed

Context

I am working to add Sensu Go 6.2 support to sensu-puppet module and during testing was unable to make use of newly added scheduler property.
