PhpStorm CSSO File Watcher: Error after save

Question

I've installed CSS minifier as the official PhpStorm documentation suggests, but this error occurred:

cmd.exe /D /C call C:\Users\douglas\AppData\Roaming\npm\csso.cmd -i styles-rca.css -o styles-rca.min.css
C:\Users\douglas\AppData\Roaming\npm\node_modules\csso-cli\node_modules\clap\lib\index.js:1
import { basename, extname } from 'path';
   ^

SyntaxError: Unexpected token {

Below is the config I'm using.

PHPStorm: 2022.2.3

csso-cli: 4.0.1

Looks similar to https://github.com/css/csso-cli/issues/28; I'd suggest downgrading csso-cli
