502 Bad Gateway - Sap Web Dispatcher as a target used in AWS Load Balancer

 Issue: 502 Bad Gateway is issued for any request which is issued to a SAP Web Dispatcher that sits behind  AWS Application load balancer.

Solution: Under the Target group defined in the AWS load balancer for the SAP Web dispatcher, ensure correct protocol version is defined.

You need to switch between the HTTP1/HTTP2 based on your version.
