無法運行任務的驗證字符串爲空

Question

我想在Amazon EC2上創建的Postgres SQL作爲簡單的任務具有以下JSON配置：

{ 
    "requiresAttributes": [], 
    "taskDefinitionArn": "arn:aws:ecs:us-east-1:870465292454:task-definition/Application:2", 
    "networkMode": "bridge", 
    "status": "ACTIVE", 
    "revision": 2, 
    "taskRoleArn": null, 
    "containerDefinitions": [ 
    { 
     "volumesFrom": [], 
     "memory": 512, 
     "extraHosts": null, 
     "dnsServers": null, 
     "disableNetworking": null, 
     "dnsSearchDomains": null, 
     "portMappings": [ 
     { 
      "hostPort": 5432, 
      "containerPort": 5432, 
      "protocol": "tcp" 
     } 
     ], 
     "hostname": null, 
     "essential": true, 
     "entryPoint": null, 
     "mountPoints": [], 
     "name": "postgres", 
     "ulimits": null, 
     "dockerSecurityOptions": null, 
     "environment": [ 
     { 
      "name": "POSTGRES_PASSWORD", 
      "value": "*******" 
     } 
     ], 
     "links": [], 
     "workingDirectory": null, 
     "readonlyRootFilesystem": null, 
     "image": "postgres", 
     "command": null, 
     "user": null, 
     "dockerLabels": null, 
     "logConfiguration": null, 
     "cpu": 0, 
     "privileged": null, 
     "memoryReservation": null 
    } 
    ], 
    "placementConstraints": [], 
    "volumes": [ 
    { 
     "host": { 
     "sourcePath": "/var/lib/postgresql/data" 
     }, 
     "name": "PGDATA" 
    } 
    ], 
    "family": "Application" 
} 

但是當我嘗試運行這個任務，我得到作爲來自服務器的響應的「Unable to run task The validated string is empty」。

有人可以幫助我瞭解我在這裏失蹤。

該錯誤消息是非常工資...但我得到這個錯誤信息之前我已配置我的羣集。確保在創建任務時選擇了羣集。
