Unknown error, the response body from fetch is: undefined

I am using in Node.js the following versions “amazon-cognito-identity-js”: “^2.0.29”, “node-fetch”: “^2.2.0”,

I am trying to signUp and authenticateUser in my app.

Initially I was getting “fetch undefined” when I call singUp. Which was fixed by adding the node-fetch library. Now I can successfully signUp users.

Now I am getting the error “Unknown error, the response body from fetch is: undefined” when I call authenticateUser method. The code is as following.

`app.post(‘/login’, (req, res) => { var authenticationData = { Username: req.body.email, Password: req.body.password, };

    var authenticationDetails = new AmazonCognitoIdentity.AuthenticationDetails(authenticationData);

    var userData = {
        Username: req.body.email,
        Pool: userPool
    };

    var cognitoUser = new AmazonCognitoIdentity.CognitoUser(userData);
    cognitoUser.authenticateUser(authenticationDetails, {
        onSuccess: function (result) {
            var accessToken = result.getAccessToken().getJwtToken();

            /* Use the idToken for Logins Map when Federating User Pools with identity pools or when passing through an Authorization Header to an API Gateway Authorizer*/
            var idToken = result.idToken.jwtToken;
        },
        onFailure: function (err) {
            console.log(err);
        }
    });`

I removed the remember device and set it to no. It worked.
