I cannot seem to start-up the python -m matrix_puppeteer_line after all of the configurations:

This is on a headless server, any ideas of how to circumvent this?

Yes, an X server is needed, as Puppeteer cannot be run headless with extensions enabled in Chrome (doc).

What should work is running an X server in the background. Some options for doing so are given here: https://stackoverflow.com/questions/32156691/running-a-program-with-gui-without-displaying-in-ubuntu.

Once I find a way of doing this that works, I'll add it to SETUP.md. Rest assured that I certainly want this bridge to work on headless servers.

Hmm, I see that chrome has built-in headless. Does it not work with extensions?

I haven't tried using the flag directly, but I did try using Puppeteer's headless mode, which I believe sets that flag itself. Doing so prevents the LINE extension from being loaded, unfortunately.

Hmm, that's unfortunate. So until that's solved we'll use something like xvfb? Are there many adjustments needed to get that working?

I assume no adjustments are needed, but I haven't tried it yet.

I've confirmed that xvfb-run node src/main.js gets it working

Great, thanks for confirming!
I'll update SETUP.md to mention this.
