S3 GetObject does not return response

I am trying to fetch an object from a s3 bucket. However I don't get a response, but also no error logged in the console.

function test(filename) {
        return new Promise((resolve => {

            var params = {
                 Bucket: bucket, 
                 Key: "pptSource/"+filename
            };

            s3.getObject(params, function(err, data) {
                // Handle any error and exit
                if (err) {
                    console.log(err);
                }

              resolve(data.Body);
            });
        }));
    }

I call the function in following function:

exports.handler = async (event) => {

        function test(filename) { .. }

        async function run() {
                var sourceFile = "XX_company_presentation_2019_v1~1-2.pptx";
                var filename = sourceFile;

                var pptSource = await test(filename);
                console.log(pptSource);
        }

        run();
}

and get following log

So, basically you are not waiting for the run function to complete.

Change it to 

await run();

This will wait for the Promise to resolve
