LAMBDA_RUNTIME Failed to get next invocation. No Response from endpoint

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!!!
