Error: `Message: Cannot read property 'Bucket' of undefined`

Message:
    Cannot read property 'Bucket' of undefined

I'm getting this error message on execute.

const
  gulp = require( "gulp" ),
  awsPublish = require( "gulp-awspublish" ),                                   
  cloudfront = require( "gulp-cloudfront" ),
  aws = {
    key:"",
    secret: "",
    distributionId: "",
    bucket: "",
    region:""
  },
  envFlag = "dev";

gulp.task( "toS3:dev", () => {
  const publisher = awsPublish.create( aws );
  return gulp.src( "./src/dist/**" )             
    .pipe( awsPublish.gzip() )
    .pipe( publisher.publish( {
      "x-amz-acl": "public-read",
      "Cache-Control": ( envFlag === "prod" ? "max-age=3600" : "max-age=120" )
    }))              
    .pipe( publisher.cache() )
    .pipe( awsPublish.reporter() )
    .pipe( cloudfront( aws ) );
});

Same problem here, haven't figured out how to fix it. All I know is publisher.create(aws) the one at fault.

Edit:
This error comes from gulp-awspublish, not from gulp-cloudfront. However, gulp-cloudfront's documentation gives an improper example of the configuration of the JSON.

At any rate, problem is solved by using the proper JSON structure for your aws object:

{
    "accessKeyId": "YOURID",
    "secretAccessKey": "YOURSECRET",
    "region": "YOURREGION",
    "distributionId": "YOURDISTRIBUTIONID",
    "params": {
        "Bucket": "YOURBUCKETNAME"
    }
}

Actually it looks like it's trying to use the same config... I'll have to split it into two configs blocks with the same data... womp womp.
