Publishing from AWS lambda to Kinesis Process exited

Question

I am trying to publish events from aws lambda but I get the following error:

Process exited before completing request

Here's my code

exports.handler = (event, context, callback) => {
  kinesis.PutRecord({
    "Data": event,
    "PartitionKey" : "1",
    "StreamName": "TestStream"
  });
  context.done();
  callback(null, "");
}

Answer 1

You have context.done called before the callback function where both are exit callbacks for the handler code. Remove context.done in your code, and also do the following change.

const AWS = require('aws-sdk');
const kinesis = new AWS.Kinesis({apiVersion: '2013-12-02'});

exports.handler = (event, context, callback) => {
  kinesis.putRecord({
   "Data": event,
   "PartitionKey" : "1",
   "StreamName": "TestStream"
   }, 
   function(err, data) {
    if (err)
      console.log(err, err.stack); // an error occurred
    else  
      callback(null, data);        // successful response
   });
}
