problem with passing the $request and $employeeId variables

[ghost]

I have a problem with passing the $request and $employeeId variables:

When I call the script, I get a list of all records (no filtering by $employeeId).

It looks like it is reading over the if statement.

web-File

Route::get('employee_course_overview/{employeeId}', [LeatroController::class, 'employeeCoursesOverview'])->name('employeeCourseOverview');

LeatroController

` public function employeeCoursesOverview(Request $request, $employeeId)

{

    if ($request->ajax()) {

        $data = Leatro::join('employees', 'employees.persnum', '=', 'leatros.employee_id')
            ->where('employees.persnum', $employeeId);
       
        return Datatables::of($data)
            ->addIndexColumn()
            ->make(true);
    }

    return view('rowdatas.leatros_employee_overview.coursesOverview');

}`
