Proxying terminal-based network traffic

I'm using gnome-terminal in mint and burp proxy with the settings below.

I can point web browsers to burp and it works, plus commands like wget use the environment vars... but my calls to nodejs aren't showing up in the proxy log.

Is there something else in the system I could to change that might encompass node's traffic?

$ gsettings set org.gnome.system.proxy.https host '127.0.0.1' $ gsettings set org.gnome.system.proxy.https port 8080 $ gsettings set org.gnome.system.proxy mode manual $ gsettings set org.gnome.system.proxy.http enabled true $ gsettings set org.gnome.system.proxy.http host '127.0.0.1' $ gsettings set org.gnome.system.proxy.http port 8080 $ gsettings set org.gnome.system.proxy.http use-authentication false $ export http_proxy=http://127.0.0.1:8080 $ export HTTP_PROXY=http://127.0.0.1:8080
