Too few arguments to function PragmaRX\Tracker\Vendor\Laravel\Models\Session::users()

Hi antonioribeiro.
I use your package and get this error:

Too few arguments to function PragmaRX\Tracker\Vendor\Laravel\Models\Session::users(), 0 passed in Path\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Builder.php on line 581 and exactly 2 expected

my laravel's version is 5.7
what is the problem? what do you think?
best regard

Start by inspecting Session::users() and the Laravel Eloquent\Builder call reported at framework/src/Illuminate/Database/Eloquent/Builder.php line 581. Reproduce the error with Laravel 5.7 and determine why users() receives no arguments despite requiring two; done means identifying the compatibility problem and the expected change.
