AWS Firehose putRecord with Lambda

fh-putrecord.js

console.log('starting lambda')

var AWS = require("aws-sdk");
AWS.config.update({region: 'us-west-2' });

var fh = new AWS.Firehose();

exports.handler = function(event, context){

fh.putRecord(
{
    DeliveryStreamName:'my-logs', 
    Record: {Data: new Buffer(JSON.stringify({foo:'bar'})) }
    
}, 
function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
  context.done(err, data)
});

}

Thanks a ton. Saved my time :-)

I tried the same solution in non-lambda application. It's not working.
can you please help how can use this solution in ECS (non-lambda).
