Description
Hi guys!
I just writing some lambdas in c++ using the aws-lambda-cpp
i checking my log and i have this Error in my log:
>
[ERROR] [1553201323958] LAMBDA_RUNTIME Failed to get next invocation. No Response from endpoint
do you know if this is normal? because i check and debug my code but i don't found nothing.
what my lambda do is extract the body from SQS request, and make a slack post with the message.
for that i use curl and have the ssl disable
other thing is i dont see a print message that i have in the main after the
```
invocation_response handler(invocation_request const &req) {
return invocation_response::success();
}
```
this is my main:
```
int main() {
//use AWS namespace and libs
using namespace Aws;
//set the log for the sdk
SDKOptions options;
//init AWS API
InitAPI(options);
{
auto handler_function = [](aws::lambda_runtime::invocation_request const &req) {
return handler(req);
};
run_handler(handler_function);
}
// shutdown the aws api
std::cout << "ShutdownAPI api" << "\n";
ShutdownAPI(options);
std::cout << "exit" << "\n";
//exit
return 0;
}
```
i dont see the Shutdown and exit print in the cloud-watch log
so the question
the ShutdownAPI(options); and the return 0 is never called?
thank you!!!

Research direction
Start with the reported LAMBDA_RUNTIME log and the main function's run_handler entry point, then trace whether handler(req) returns and where ShutdownAPI is reached. Confirm the expected lifecycle from the runtime behavior and document what should be visible in CloudWatch; done means the endpoint message and missing prints are explained.
