I have a react project that tried to switch to AWS Amplify Authenticator, but got errors: Unhandled Rejection (Error): register failed, invalid key $$typeof from plugin /src/app.tsx.

The error message you’re seeing typically indicates that there’s an issue with the configuration of AWS Amplify in your project. The $$typeof key is a property added by React for security reasons, and it should not interfere with the Amplify configuration.

Ensure that Amplify is configured correctly in your project. You should import the aws-exports.js file and pass it to Amplify.configure(). Also check if the versions of aws-amplify and @aws-amplify/ui-react you’re using are compatible with each other and reinstall Node Modules
