mistake

author , please tell me,when executing the following command I get this error:
editly, /home/JobId_1.json5, --width, 900, --height, 506

Error: gl returned null, this probably means that some dependencies are not installed. See README.

Are you running on a headless linux instance? Make sure xvfb is installed and running. See https://github.com/stackgl/headless-gl?tab=readme-ov-file#how-can-headless-gl-be-used-on-a-headless-linux-machine
