使用框架: React

复现步骤

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?

index.esm.js?eb04:2657 Uncaught (in promise) TypeError: Cannot read property 'componentDidShow' of undefined
    at Route.componentWillReceiveProps (index.esm.js?eb04:2657)
    at eval (index.esm.js?eb37:1900)

    at patchChildren (index.esm.js?eb37:1064)
    at patch (index.esm.js?eb37:987)

期望结果

在异步回调里能成功调用Taro.redirectTo方法

实际结果

报错：

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