change protocol of endpoint in AMFChannel, how to fix it? - actionscript-3

Question

I am working on Flex and I find that when I give uri(https://jsonplaceholder.typicode.com/posts/1) to AMFChannel which content 'HTTPS' protocal but calculateEndpoint() method of Channel class change protocol from "HTTPS" to "HTTP".
I also made simple project to demonstrate how endpoint gets changed by AMFChannel.

Instead of AMFChannel use SecureAMFChannel as below
var amfChannelWeb:SecureAMFChannel = new SecureAMFChannel("amfChannel", txtInput.text);
