getStatus() return 0!

[Padandish]

Hi dears,
I used php-phantomjs on Windows 10, it work greatly!
Now

I used
Ubuntu 18.04 server
PHP 7.4.13
phantomjs 2.1.1
export QT_QPA_PLATFORM=offscreen to phantomjs

but when call $response->getStatus() returned 0!;

I do document test-script.js from commandline, it's OK!

I try enable log:
sh: 1: /root/myfolder/bin/phantomjs-run: not found

but validateExecutable() in Engine.php return true!

How fix it?
