Unable to verify secret hash for client in Amazon Cognito Userpools

Question

I am stuck at "Amazon Cognito Identity user pools" process.

I tried all possible codes for authenticating user in cognito userpools. But I always get error saying "Error: Unable to verify secret hash for client 4b*******fd".

Here is code:

AWS.config.region = 'us-east-1'; // Region
AWS.config.credentials = new AWS.CognitoIdentityCredentials({
    IdentityPoolId: 'us-east-1:b64bb629-ec73-4569-91eb-0d950f854f4f'
});

AWSCognito.config.region = 'us-east-1';
AWSCognito.config.credentials = new AWS.CognitoIdentityCredentials({
    IdentityPoolId: 'us-east-1:b6b629-er73-9969-91eb-0dfffff445d'
});

AWSCognito.config.update({accessKeyId: 'AKIAJNYLRONAKTKBXGMWA', secretAccessKey: 'PITHVAS5/UBADLU/dHITesd7ilsBCm'})

var poolData = { 
    UserPoolId : 'us-east-1_l2arPB10',
    ClientId : '4bmsrr65ah3oas5d4sd54st11k'
};
var userPool = new AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool(poolData);

var userData = {
     Username : '[email protected]',
     Pool : userPool
};

var cognitoUser = new AWSCognito.CognitoIdentityServiceProvider.CognitoUser(userData);

cognitoUser.confirmRegistration('123456', true,function(err, result) {
if (err) {
    alert(err);
    return;
}
console.log('call result: ' + result);
});

It seems that currently AWS Cognito doesn't handle client secret perfectly. It will work in the near future but as for now it is still a beta version.

For me it is working fine for an app without a client secret but fails for an app with a client secret.

So in your user pool try to create a new app without generating a client secret. Then use that app to signup a new user or to confirm registration.
