laravel server monitor return General Error and last_run_message return Exception occurred: Pattern `/(\d?\d)%/` with subject `` didn't capture a group named 1

I'm developing a server mounting application using the laravel spatie-monitor package, but I've been stuck for a while at the stage of checking metrics at the server level. For example, when I run a diskspace check, $process->getOutput() returns an empty string and in exit_code_text I get a General Error. Could you tell me what the problem is, please? I was able to see that this issue was raised a few years ago.
