How to upload an object into S3 in Lambda?

Question

Can\'t seem to upload an object into S3 in Lambda. Everything works fine locally. No errors in logs that would show what\'s going wrong...

Code below:

I suspect you are calling the context.done() function before s3.upload() has a chance to return. If you move context.done() into the upload response code block, it should work.

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

exports.handler = function(event, context) {
    //console.log(JSON.stringify(event, null, 2));
    var s3 = new AWS.S3();
    var param = {Bucket: 'flow-logs', Key: 'test-lambda-x', Body: 'me me me'};
    console.log("s3");
    s3.upload(param, function(err, data) {
        if (err) console.log(err, err.stack); // an error occurred
        else console.log(data);           // successful response

        console.log('actually done!');
        context.done();
    });

    console.log('done?');
    //context.done();
};
