        $command = call_user_func_array("sprintf", $parameters);

        exec($command, $output);

        return $output;

The expression return $output; of type null|array is incompatible with the return type declared by the interface AsyncPHP\Doorman\Shell::exec of type string as it can also be of type array which is not included in this return type.
