Https response using pubclienthttp


I have a calling flow service as below

bytestoString (of response string)

and called flow service as

Map - setting value of a string variable

When I call the service using http://url:5555/invoke/service, I can see the response in the string after bytestoString, but when I call using https://url:443/invoke/service, it gives me 200 OK, but the string is empty.

Is it for https calls using the pub.client:http flow, you need to do some decoding of response to get the actual response or does it handle all the ssl logic.
