Extension Helper Library not loaded

[ankitpal1029]

@lleadbet i ran the webpack server with this setting

    config.devServer = {
      contentBase: path.join(__dirname, "public"),
      host: argv.devrig ? "localhost.rig.twitch.tv" : "localhost",
      allowedHosts: [".lhrtunnel.link"],
      compress: true,
      headers: {
        "Access-Control-Allow-Origin": "*",
      },
      port: 8080,
    };
    config.devServer.https = false;

and served the port 8080 over localhost.run to get a https link which i pasted into twitch like this

despite all this i get an empty extension space

with the Extension Helper Library not loaded
can you help me out in getting this setup for local testing?
i tried building it and using on hosted testing and that seemed to work

turns out it was the tunneling service i was using that was messing up
