I tried to test the export of my project written in C# using Godot headless version with this command:

root@vps-22-03-19-21-35-00-674:/home/ubuntu/Godot_v3.4.3-stable_mono_linux_headless_64# godot --path mascot --build-solutions --export-debug "Linux/X11" "/builds/linux/mascot"

But got the errors:

Godot Engine v3.4.3.stable.mono.official.242c05d12 - https://godotengine.org
WARNING: Started the engine as `root`/superuser. This is a security risk, and subsystems like audio may not work correctly.
Set the environment variable `GODOT_SILENCE_ROOT_WARNING` to 1 to silence this warning.

I have no ideal what I should do next, as the error didn’t say anything specific.
Any ideal what should I do? or what I do wrong? or Am I missing any step in this path?

I’m not doing things in Mono/C# and I haven’t tested more complicated commands for testing like this, but I think the takeaway is there are a bunch of failed attempts to import graphical things like textures in those errors. Which is not what a headless executable should do; the whole point is you save resources by ignoring the graphical stuff in your export. Make absolutely sure (i.e. maybe rewrite the command or uninstall unnecessary godot things) that you are running the headless-server executable and you’ve got the right game .pck on the server.

If you are running the correct executable, my understanding is it shouldn’t even try to open these graphical imports, but obviously it is and that’s an issue.

p.s. If it’s an option for you, creating even a tiny linux vm for testing locally and fixing these errors might be beneficial as opposed to on a VPS.
