Valet requires Homebrew to be installed on your Mac

I'm working on a project which use nextcloud as a document manager and when i'm upload a file, I want to launch nextcloud files sync so I use envoy to manage my command.

My command works when i type it in the CLI, it works when i'm running a test of my store new document. But when I use it the normal way through the interface and add a document, the buffer logs me : Valet requires Homebrew to be installed on your Mac.

Of course I have homebrew on my Mac and i'm running anything related to valet in my task.

@servers(['localhost' => '127.0.0.1'])

@task('synchronize', ['on' => 'localhost'])
    cd {{ $path }}
    docker-compose exec -T --user www-data app php occ files:scan {{ $user }}
@endtask

As I said, it work manually and through a unit test but not when i'm using it from my interface... Any Idea ?

EDIT: Here are my logs

[2020-09-09 07:41:33] local.DEBUG: Nextcloud Syncronized
[2020-09-09 07:41:33] local.DEBUG: ["Valet requires Homebrew to be installed on your Mac."]
