AWS Cloudfront createInvalidation

I am attempting to perform CloudFront invalidation using the following code:

var cloudfront = new AWS.CloudFront({s3BucketEndpoint: <String Bucketname>});
        var params = {
            DistributionId: <String ID>,
            InvalidationBatch: {
                CallerReference: 'Cloudfront Invalidation',
                Paths: {
                    Quantity: 1,
                    Items: [
                        '/*'
                    ]
                }
            }
        };
        cloudfront.createInvalidation(params, function(err, data){
            if (err) console.log(err, err.stack); // an error occurred
            else     console.log(data);           // successful response
        });

However, I get no response in my createInvalidation function from err or data. The documentation for the AWS SDK states you should get a positive/negative response, but nothing is returned and no invalidation is performed.

The parameter "callerreference" must be unique, which allows awss3 to avoid you submitting the same request and can be used as a key timestamp

It might be your CallerReference, in the JavaScript aws-sdk docs (docs.aws.amazon.com) it says that it needs to uniquely identify the invalidation request.

I stumbled upon this question trying to do the same thing as you're doing and I was able to get the createInvalidation working with the following code:

var cloudfront = new AWS.CloudFront();

var params = {
  DistributionId: <String ID>,
  InvalidationBatch: {
    CallerReference: Date.now().toString(),
    Paths: {
      Quantity: 1,
      Items: [
        '/*'
      ]
    }
  }
};

cloudfront.createInvalidation(params, function(err, data) {
  if (err) console.log(err, err.stack);
  else     console.log('Data: ' + JSON.stringify(data));
});

The use of the Date.now().toString() gives a timestamp string that will be unique to when this code is run.

With the above code, I got an output of (after pretty formatting the json):

Data: {
  "Location": "https://cloudfront.amazonaws.com/2017-03-25/distribution/<String ID>/invalidation/<String ID>",
  "Invalidation": {
    "Id": "<String ID>",
    "Status": "InProgress",
    "CreateTime": "<Timestamp>",
    "InvalidationBatch": {
      "Paths": {
        "Quantity": 1,
        "Items": [
          "/*"
        ]
      },
      "CallerReference": "<Timestamp>"
    }
  }
}
