AWS Lambda Destinations not working

[pkonstanczuk]

Hello I am using Lambda C++ SDK with success in our environment but when i connect Destination (SQS on both failure and success) the result is not send to the queue.
I am returning the outcome by
return aws::lambda_runtime::invocation_response::success(output, "application/json");

Tested the queue with other Lambda(Python) with the same security settings and it then works fine so i believe there may be sth wrong within aws-lambda-cpp.
Thank you!
