Running "mup deploy" with mup-aws-beanstalk results in "Unable to load plugin mup-aws-beanstalk ReferenceError: regeneratorRuntime is not defined"

Im trying to deploy a project to AWS with Meteor Up plugin mup-aws-beanstalk. Instructions are pretty simple. Install plug in, get some info from your AWS account, modify a file with stuff related to your project, run the deploy command "mup deploy". Docs are here https://github.com/zodern/mup-aws-beanstalk/blob/master/docs/getting-started.md

After running the deploy command, I get this error/output

    PS C:\Users\Arsla\OneDrive\Desktop\Greg\radgrad2\app\.deploy> mup deploy

I tried reinstalling mup and mup-aws-beanstalk, but that didnt work. My env.MONGO_URL might be wrong, but I'm not sure how to check. The id and secret have been replaced with appropriate information.

this is the file I modded: .deploy/mup.js

module.exports = {
app: {
    // Tells mup that the AWS Beanstalk plugin will manage the app
    type: 'aws-beanstalk',
    name: 'radgrad2',
    path: 'C:\Users\Arsla\OneDrive\Desktop\Greg\radgrad2\app\.deploy',
    env: {
        ROOT_URL: 'http://localhost:3200/', 
        MONGO_URL: 'mongodb://localhost:27017/radgrad2' //not sure about this, but localhost:27017 is the default local host for MongoDB
    },
    auth: {
        id: '12345', // provided by AWS
        secret: '6789' // provided by AWS
    },
    minInstances: 1
},
plugins: ['mup-aws-beanstalk']
};

Where should I look for the source of the error?

I googled for the error, and it looks like this was fixed two days ago.

Are you running 0.6.4 of the plugin and mup 1.5? If so, then you probably want to reopen that issue.
