启动后从v1迁移到v2后，我在Android上遇到了Invariant Violation。我该如何解决？
Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object.
Check the render method of `ReduxWrapper`.
This error is located at:
in ReduxWrapper (at renderApplication.js:35)
in RCTView (at View.js:45)
in View (at AppContainer.js:98)
in RCTView (at View.js:45)

我已经尝试隔离问题，并检查是否采取了正确的步骤进行迁移，但是我无法找出问题所在。
import {Provider} from "react-redux";
import {Navigation} from "react-native-navigation";
import {registerScreens} from "./screens";
import configureStore from "./store/configureStore";
export const store = configureStore();
registerScreens(store, Provider);
Navigation.events().registerAppLaunchedListener(() => {
initApp().then(() => {
Navigation.setRoot({
root: {
stack: {
children: [{
component: {
name: "app.Login"
}
}],
options: {
topBar: {
title: {
text: ""
}
}
}
}
}
}).catch(function (reason) {
console.error("Screen creation failed", reason);
}); }
);
});
async function initApp() {
...
}
这是index.android.ts文件。
import {Navigation} from "react-native-navigation";
import LoginController from "./modules/controller/LoginController";
export function registerScreens(store: any, provider: any) {
Navigation.registerComponentWithRedux("app.Login", () => LoginController, store, provider);
}
这是screens.ts文件。

我遵循了迁移指南，并希望它能正常工作。

答案 0 :(得分：2)
我发现了错误。 我使用了过时的方式注册屏幕。我认为已弃用意味着仍在工作。
Navigation.registerComponentWithRedux("app.Login", () => LoginController, store, provider);
应该是：
Navigation.registerComponent("app.Login", () => (props) => (
<Provider store={store}>
<LoginController {...props} />
</Provider>
), () => LoginController);
