title: sam local start-lambda - how to send send s3 event to sam local endpoint
body: <p>I can invoke a local lambda http endpoint (sam local start-lambda), but how do I trigger that lambda endpoint with a (mock) AWS event (s3, etc.) like I can when using the Dockerized lambda environment (sam local invoke -e event.json myLambdaFunction)?  </p>
  
  <p>I want to trigger an s3 event on the locally running lambda endpoint just like I can on a lambda deployed to AWS.</p>
