Hangs on Mac mini M2 headless

[ubmarco]

I am running tests for a VS Code extension on a self-hosted Github runner. The runner is installed on an Mac mini M2 ARM architecture. The Mac has a display connected, but no user is logged in during the test. I also don't want to connect a display for productive usage.

Run coactions/setup-xvfb@v1
/opt/homebrew/bin/npm test
> new_ext@0.1.1 test
> npm run compile && npm run test:compile && vscode-test --timeout=5000
> new_ext@0.1.1 compile
> npm run check-types && node esbuild.mjs
> new_ext@0.1.1 check-types
> tsc --noEmit
[watch] build started
[watch] build finished
> new_ext@0.1.1 test:compile
> node esbuild-tests.mjs

It hangs at this step for a couple of minutes until the Github action times out. Any clue what's wrong?

The error also appears when I connect to the machine via SSH and run it locally outside of a github action. And without coactions/setup-xvfb.

It just returns

and hangs there forever.
