CI 4.5.4 works. Errors is empty or show "The email field must contain a valid email address":

        $this->validateData(
            [
                // 'email' => 'test@mail',
                // 'email' => '',
            ],
            [
                'email' => 'valid_email|permit_empty',
            ]
            );

        var_dump(
            'Debug: ',
            $this->validator->getErrors()
        );
