Command line can not be null

[ghost]

Hello I want to start a LoadBalanced Request in Singularity and everytime when I deploy it it says Command line can not be null REVERTING
How can I stop that?

Baragon displays my two agent and one is the master so I think that they working correctly.

My Singularity Request:

{
"deploy": {
        "requestId": "Nginx",
        "id": "20",
        "containerInfo": {
          "type": "DOCKER",
          "docker": {
            "image": "nginx",
            "privileged": false,
            "network": "BRIDGE",
            "portMappings": [
              {
                "containerPortType": "LITERAL",
                "containerPort": 80,
                "hostPortType": "FROM_OFFER",
                "hostPort": 0,
                "protocol": "tcp"
              }
            ],
            "forcePullImage": false
          }
        },
        "resources": {
          "cpus": 1,
          "memoryMb": 1024,
          "numPorts": 1,
          "diskMb": 0
        },
        "serviceBasePath": "/",
		"loadBalancerGroups": [
    		"loadBalancerGroupName"
		],
        "shell": false
   }
}

The group exists and the base path is after the request visible.
