MagicMirror loading fails behind reverse proxy after upgrading to v2.29 due to missing environment variables #3613
Description
Platform: Raspbian GNU/Linux 11 (bullseye) on Raspberry Pi 2
Node Version: 22.11.0
MagicMirror² Version: 2.29.0
Description: After upgrading MagicMirror from v2.28.0 to v2.29.0 my web interface won't display anything. Turning on developer tools displays missing /env subpath resulting in an exception in loader.js / main.js and subsequent loading.
Steps to Reproduce: I use a nginx webserver, which uses a reverse proxy on /apps/MagicMirror to redirect it to hostname:8080. My config.js has the reverse proxy included.
let config = {
address: "0.0.0.0",
port: 8080,
// basePath: "/",
basePath: "/apps/MagicMirror/", // The URL path where MagicMirror² is hosted. If you are using a Reverse proxy
// you must set the sub path here. basePath must end with a /
...
};Expected Results: As for previous versions socket.io uses the basePath to establish socket connection between client and server. The initial loading for loading environment variables should, too.
Actual Results: MagicMirror loading fails. As a workaround I modified loader.js to
const res = await fetch(`${location.protocol}//${location.host}/` + config.basePath + `/env`);in order to make my application work again. Probably needs further refinement and exception handling.
