How to use the @feathersjs/commons.omit function in @feathersjs/commons

return function (req, res, next) {
      const { query } = req;
      const route = omit(req.params, '__feathersId');

      res.setHeader('Allow', allowedMethods.join(','));

      // Check if the method exists on the service at all. Send 405 (Method not allowed) if not
      if (typeof service[method] !== 'function') {
        debug(`Method '${method}' not allowed on '${req.url}'`);
        res.status(statusCodes.methodNotAllowed);

        return next(new errors.MethodNotAllowed(`Method \`${method}\` is not supported by this endpoint.`));
      }

      // Grab the service parameters. Use req.feathers
      // and set the query to req.query merged with req.params
      const params = Object.assign({
        query, route
      }, req.feathers);
