Cannot read property 'then' of undefined
在执行deleteMenu()的时候，deleteMenu()里面的then错误，这是为什么？
Wechat.prototype.deleteMenu = function(){
var that = this
return new Promise(function(resolve, reject){
that
.fetchAccessToken()
.then(function(data){
var url = api.menu.del + 'access_token=' + data.access_token
request({method: 'GET', url: url, json: true}).then(function(response){
var _data = response.body
if (_data) {
resolve(_data)
}
else{
throw new Error('Get menu fails')
}
})
.catch(function(err){
reject(err)
})
