AWS Amplify: How to setup { withConnector } component?

问题

Following the Amplify Quick Start I set up an AWS Mobile App with the awsmobile-cli:

awsmobile init
awsmobile user-signin enable
awsmobile push

In my react App I configured Amplify like so (I also tried manual configuration):

import Amplify from 'aws-amplify';
import aws_exports from '../../aws-exports.js';
Amplify.configure(aws_exports);
import { withAuthenticator } from 'aws-amplify-react';

...
export default withAuthenticator(App);

This Code shows me the Cognito UI, but on any action, I take the following error appears:

No userPool

How do I properly connect the Amplify withConnector component with my App's userPool?

P.S. Yesterday evening my app was working flawlessly. Today I only performed some minor changes and cannot explain this behavior.

Can you check if there is aws-amplify under your node_modules/aws-amplify-react/node_modules. Sometimes npm will install it twice and caused some problem
