v4.4.4 download not working, v4.1.1 does work

Code:

public function file_view($year, $employee_number, $file_type) {





        if ($employee_number != 0) {

            $wellnessModel = new \App\Models\WellnessAttestationModel();

            $result = $wellnessModel->findLastYears($employee_number, $year);

        } else {

            $benefitProgramModel = new \App\Models\BenefitProgramModel();

            $result = $benefitProgramModel->find($year);

        }

        if (empty($result)){

            return "No file to download.";

            die();

        }

        if ($file_type == "CCCL") {

            $file_path = trim($result['Cessation_Completion_Cert_Location']);

        } else if ($file_type == "CPFL") {

            $file_path = trim($result['Cessation_Proof_Enrollment_Location']);

        } else if ($file_type == "PAL") {

            $file_path = trim($result['Physician_Affidavit_Location']);

        } else if ($file_type == "PALF") {

            $file_path = trim($result->Physician_Affidavit_Template_Location);

        } else {

            return false;

        }

        return $this->response->download($file_path, NULL, TRUE);

    }

Code:

$routes->group('wellness', static function ($routes) {

    // GET routes, alphabetized

    

    $routes->get('file_view/(:any)', 'Wellness::file_view/$1');

}
