This method seems to be duplicated in your project.

        $field = $this->fields->getField($parameter);
        if (!($field instanceof CliField)) {
            $fieldClass = get_class($field);
            throw new \Exception("Not a CliField [$fieldClass]");
        }
        return $field;
    }
}
