invocation_response::failure does not work with HTTP API Gateway ? #117
Description
I'm using the HTTP API Gateway, my c++ runtime is built with amazonlinux:latest in a docker image.
All responses that return with invocation_response::failure return an Error 500, Internal Server Error.
#include <aws/lambda-runtime/runtime.h>
using namespace aws::lambda_runtime;
static invocation_response my_handler(invocation_request const& req)
{
return invocation_response::failure("error message here"/*error_message*/, "error type here" /*error_type*/);
}
int main()
{
run_handler(my_handler);
return 0;
}
However, when I use invocation_response::success, the message arrives on my requesting client, but I ofc. can only send json objects back. (Anyone got an idea why that is ?)
I read everything google found and digged through all kinds of files and aws docus, I could not find out where the problem is. Could someone please give me a hint if the args have to match some specific ones or what I am doing wrong ?
Thanks!

I am having the same issue. Did you ever figure this out?

The API Gateway example produced an internal server error even when I posted successful responses. I think it is because I created a REST API gateway.
What I found is that the API Gateway expects a specific response structure. When I used this structure my successful responses worked.
So it seems that when you use
invocation_response::failureyou report to the API Gateway that you cannot reply to this request. It then emits a500If you want to send a
400error to the caller, you should includestatusCode: 400as part of the response structure and useinvocation_response::successto send the structure through.So maybe the solution is to switch to a REST API instead of an HTTP API?
