You must define a binary prior to conversion. Snappy for Laravel 9 - wkhtmltopdf

Question

I've got this LogicException with Laravel 9 on Mac OS Monterey 12.3.1.
I have download wkhtmltopdf binary
Check binary path (/usr/local/bin/wkhtmltopdf and /usr/local/bin/wkhtmltoimage)
Make a chmod +x to binaries
Install composer package via composer require barryvdh/laravel-snappy
Adding config snapy via php artisan vendor:publish --provider="Barryvdh\Snappy\ServiceProvider"
define to my .envfile needed variables (WKHTML_PDF_BINARY & WKHTML_IMG_BINARY)
This is my snappy.php file for config : (automaticly generated)
<?php
return [
/*
|--------------------------------------------------------------------------
| Snappy PDF / Image Configuration
|--------------------------------------------------------------------------
|
| This option contains settings for PDF generation.
|
| Enabled:
|
| Whether to load PDF / Image generation.
|
| Binary:
|
| The file path of the wkhtmltopdf / wkhtmltoimage executable.
|
| Timout:
|
| The amount of time to wait (in seconds) before PDF / Image generation is stopped.
| Setting this to false disables the timeout (unlimited processing time).
|
| Options:
|
| The wkhtmltopdf command options. These are passed directly to wkhtmltopdf.
| See https://wkhtmltopdf.org/usage/wkhtmltopdf.txt for all options.
|
| Env:
|
| The environment variables to set while running the wkhtmltopdf process.

I also try to clean Laravel's cache.
What I've missed ? According to the official documentation nothing is needed anymore but it doesn't work anyway.
