I built and deployed the endpoints-frameworks-v2/backend sample project following instructions in the latest Readme. Build and deployment were successful. Received Bad Gateway 502 response with sample curl request. Cloud console error detail is

@meggieclub are still seeing this issue?
If so, could you please check if the current version of the sample now works?
