Taro.redirectTo bug

异步调用调用Taro.redirectTo不能正常跳转

在app.jsx的componentDidMount钩子里异步调用Taro.redirectTo方法会报错，同步调用则不会

// app.jsx
class App extends Component {
    componentDidMount () {
        console.log('app mount')
        setTimeout(() => {
          Taro.redirectTo({url: '/pages/index/index'});
        });
    }
}

报错栈：

index.esm.js?eb04:2680 showPage:fail Received a falsy component for route "/pages/index/index". Forget to export it?
