Jenkins推送部署应用引擎失败

Question

我正在尝试使用Google官方documentation配置推送部署。我在下面收到字段违规，但是，我的app.yaml文件似乎格式正确。

ERROR: (gcloud.preview.app.deploy) Error Response: [400] Request contains an invalid argument.

        },
        {

          "field": "version.handlers[1].url_regex"
        },

        }
      ]
    }
  ]
]
