            Error: Amplify has not been configured correctly.
            This error is typically caused by one of the following scenarios:

            1. Make sure you're passing the awsconfig object to Amplify.configure() in your app's entry point
                See https://aws-amplify.github.io/docs/js/authentication#configure-your-app for more information
            
            2. There might be multiple conflicting versions of amplify packages in your node_modules.
				Refer to our docs site for help upgrading Amplify packages (https://docs.amplify.aws/lib/troubleshooting/upgrading/q/platform/js)

            This error is typically caused by one of the following scenarios:

            1. Did you run \`amplify push\` after adding auth via \`amplify add auth\`?
                See https://aws-amplify.github.io/docs/js/authentication#amplify-project-setup for more information

            2. This could also be caused by multiple conflicting versions of amplify packages, see (https://docs.amplify.aws/lib/troubleshooting/upgrading/q/platform/js) for help upgrading Amplify packages.
