nope. It seems this happened due to ghost-cli can not get access to this ghost instance. Because if I run ghost command in another ghost instance, everything went just fine as long as I don’t get the other instance’s information (like run ghost ls would cause trouble).
Can you try running sudo systemctl is-active ghost_xxx-com and seeing if the command fails? I’m curious to see if there’s an issue with your systemd service or if something’s wonky in the CLI
