I'm unable to get AWS Amplify to authenticate to my AWS Cognito setup. I use the following code to set up.

import Amplify from 'aws-amplify-react-native';
import { Auth } from 'aws-amplify-react-native';

Amplify.configure({
    Auth: {
        IdentityPoolId: 'us-west-2:XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX',
        region: 'us-west-2',
        UserPoolId: 'us-west-2_XXXXXXXX',
        ClientId: 'XXXXXXXXXXXXXXX'

    }
});

and this code to sign in

Auth.signIn(this.state.username, this.state.password)
.then(user => console.log(user))
.catch(err => console.log(err)); //"No userPool" logged here

However I get the error No userPool logged as an error.

The example here: .md has some of the configuration attributes starting with a lower case, however when I follow that I get the Red Screen.

It is just wrong config. The example in guide is:

import Amplify from 'aws-amplify';

Amplify.configure({
    Auth: {
        identityPoolId: 'XX-XXXX-X:XXXXXXXX-XXXX-1234-abcd-1234567890ab', //REQUIRED - Amazon Cognito Identity Pool ID
        region: 'XX-XXXX-X', // REQUIRED - Amazon Cognito Region
        userPoolId: 'XX-XXXX-X_abcd1234', //OPTIONAL - Amazon Cognito User Pool ID
        userPoolWebClientId: 'XX-XXXX-X_abcd1234', //OPTIONAL - Amazon Cognito Web Client ID
    }
});

I worked it out going through the AWS code, the userPoolWebClientId was required, and as Richard Zhang pointed out above I was using the wrong attributes.
