aws-sdk-js: SignatureDoesNotMatch createBucket on s3 since 2.4.*

Hello,

Thank you in advance for helping me with this issue. I have been getting SignatureDoesNotMatch error since updating to aws-sdk-js 2.4.* when trying to utilize the createBucket for s3. The following is my javascript code:

var AWS = require('aws-sdk');
AWS.config.region = "us-west-1";
s3bucket = new AWS.S3();
s3bucket.createBucket({Bucket: myNumberVarialbe + "/"},function(err,data){
                if (err) {
                    console.log("Error creating object " + emailId);
                    console.log("Request")
                    console.log(this.request.httpRequest)
                    console.log("Response")
                    console.log(this.httpResponse)
                    console.log("Error Object")
                    console.log(err);
                    console.log("Data Object")
                    console.log(data);
                }else{
                    console.log("Object " + emailId + " created.");
                    callback();
                }
            });

My AWS configuration is being determined by environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY. I have set the IAM user associated with the credentials to be in a group with AmazonS3FullAccess permissions. I have tried using new access key id and secret access key with the user, but I am getting the same errors.

The following is a result of console.log(this.request.httpRequest):
