node 8.10 async dosen't working

[aronsuarez]

When I run this code:

const AWS = require('aws-sdk')
const s3 = new AWS.S3()

exports.handler = async function(event) {
 const operation = event.operation
 let expire = null

 // Set expiration
 if (event.expires && event.expires > 600) {
 expire = 300
 } else if (event.expires && event.expires < 600) {
 expire = event.expires
 } else {
 expire = 300
 }

 const params = {
 Bucket: event.bucket,
 Key: event.key,
 Metadata: event.metadata,
 Expires: expire,
 ContentType: event.contentType,
 }

 // Create URL
 const url = s3.getSignedUrl(operation, params)

 return url
}

I god no output in the terminal (when i run the same code with callback it works), when i set a console.log('xyz') a see the log on the console but the returnes value is not showed.

I use node8.10 as runtime and i have setted the runtime also in the .env file.
