使用Pug访问嵌套数组

Question

我有以下内容正在被MongoDB拉出来，我正试图在pug中显示“url”和“applications”，来自url的数据显示正确，但是我无法从“应用程序”访问数据

                }
        ],
        "originalUrl" : "http://www.opencolleges.edu.au",
        "updatedAt" : ISODate("2017-07-26T23:23:19.756Z"),
        "__v" : 0,
        "createdAt" : ISODate("2017-07-24T10:37:50.247Z")
}

在我使用的.pug文件中：

ul.list-group
            each tech, i in techs
                    li.list-group-item
                        h5 #{tech.originalUrl}
                        h5 #{tech.applications.name}

然而，tech.applications.name的结果返回null值，当我使用tech.applications时它返回[Object，Object]是否可以使用PUG访问它？
