v1.26.2

Summary

This release addresses CORS Pre-flight issue when using Event Handler with ALB. Prior to this release, ALB would return HTTP 502 if Lambda would return a null body for a Pre-flight (HTTP OPTIONS) request. This release sets body to an empty string for compliance, and it doesn't affect API Gateway/AppSync features.

Shoutout to @francispeabody for spotting this behaviour, as CORS Specification doesn't dictate whether there should be a response or not leaving to each service to make their own judgement.
