uniapp开发时编译成微信小程序时并在小程序开发工具运行时，时而会出现：
TypeError: Invalid attempt to destructure non-iterable instance.
In order to be iterable, non-array objects must have a [Symbol.iterator]() method.
这样到报错，无法定位问题。
因为什么才会导致这样的问题。

应该是在当做数组解构吧？比如说const [err, res] = await uni.request(xxx)，之前我也遇到过，然后手动改成了这样
const [reqErr, reqResponse] = await new Promise<[UniReqError, UniReqResult]>(resolve => {
uni.request({
...requestOptions,
success: result => resolve([void 0, result as unknown as UniReqResult]),
fail: result => resolve([result, void 0 as unknown as UniReqResult]),
});
});
