preload.bundle.js protocol 'http' is not supported, expected 'https'

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

I have built Signal desktop for linux AppImage, I want to try it out by linking my android device by connecting to our development server which is running on http. According to build steps to connect to development we need to start by SIGNAL_ENABLE_HTTP=1 yarn start, initially QR code scan is getting generated and when I try to link android device and sync contacts and groups that time am getting error in preload.bundle.js as 'http' is not supported, expected 'https' , my config/production.json file has links to my server with http protocol not https. Maybe my understanding SIGNAL_ENABLE_HTTP=1 is wrong. Kindly can anyone please help me if am doing anything wrong? ###

Steps to reproduce

SIGNAL_ENABLE_HTTP=1 yarn start

Expected result

should run with http protocol

Actual result

Err: preload.bundle.js as 'http' is not supported, expected 'https'

The part of Contributing.md that talks about a 'development server' is talking about webpack-dev-server for hot-reload scenarios. And I think it's out-of-date, because I don't think there's any part of the app which supports that right now. The sticker creator used to.
