Using the async keyword in AWS Lambda

I play with AWS Lambda using Node.js. After you got tired of calling callbacks, I decided that I could elegantly use async/awaitit just like I was used to C #.

exports.handler = async(event, context, callback) => {
    db = await MongoClient.connect(process.env['MONGODB_URI']);
}

Although this seems to work when testing offline using lambda-local, it loads with an error in AWS. It seems that the keyword is asyncnot recognized. I am using the latest version of Node.js 6.10 on AWS, while my local version is 8.5. Is there a way, or should I abandon this approach and return to using callbacks?
