   description: 'Look up the specified user and welcome them, or redirect to a signup page if no user was found.',

   inputs: {
      userId: {
        description: 'The ID of the user to look up.',

        // if the `userId` parameter is not a number.
        type: 'number',
        // By making the `userId` parameter required, Sails will automatically respond with

      // Look up the user whose ID was specified in the request.
      // Note that we don't have to validate that `userId` is a number;

      // if validation fails.
      var user = await User.findOne({ id: inputs.userId });

      // If no user was found, respond "notFound" (like calling `res.notFound()`)
