uni.request 第一次请求 输出Uncaught (in promise) TypeError: undefined is not iterable!

uni-app项目，运行H5到chrome，首页的uni.request 请求数据，控制台会输出错误信息
Uncaught (in promise) TypeError: undefined is not iterable! core.get-iterator.js:5

uni.request是按照例子写的，且值有主页这个请求会报错，跳转到子页面后，在页面及其它请求并没有报错。

uni.request({
url: 'http://api.shangpibao.com/shangpibao/v2/advertise',
success: (res) => {
uni.hideLoading();
console.log(res.data)
},
fail: (res) => {
uni.showToast({title: '数据请求失败，请稍后再试！',icon:'none',uration: 2000});
},
complete: (res) => {}
});
