js部分代码如下：

Page({

data: {

id: '',

ids: '',

idss: ''

},

onLoad: function (options) {

this.setData({

id: options.id

});

// var idss=this.date.id;

var ids = this.data.id;

var that = this;

wx.request({

url: 'https://www.bbjteam.com/xiaochenxu/bbjteam/index.psdinfo.php',

method: 'POST',

data: {

ids: ids

},

header: {

'content-type': 'application/x-www-form-urlencoded'

},

success: function (res) {

that.setData({

psdinfo: res.data,

});

wx.setNavigationBarTitle({

title: that.data.psdinfo.psd_name

})

}

})

}

})

运行报错：

setNavigationBarTitle:fail parameter error: parameter.title should be String instead of Undefined;

请问大神这个应该如何解决？
