Python script execution error in Laravel controller

Currently my scripts work perfectly within the schedule that run at specific times within my server's cron.Currently my scripts work perfectly within the schedule that run at specific times within my server's cron.

The problem is occurring when I try to execute the method inside the controller, this method basically uses a shell_exec() that executes a script in python and this return is what I deal with Laravel.

When I call it from the console or the schedule it works correctly, but when I call the method or even an \Artisan::call('schedule:test'); it returns the same error saying that it is not finding the geckdriver.

The command "python C:/wamp64/www/MoneyGuard/pythonGuard/tesouro_direto/tesouro_direto_precos_taxa_titulo.py" failed.

Python Script: tesouro_direto_precos_taxa_titulo.py

From what I'm noticing when I run the command inside the controller, it is not using the path of my system. the question is why?

I thank you in advance for any help.
