Sails v1 Blueprints API query error on one-to-one attribute when there's no value

Question

After I upgrade to Sails v1, all the blueprint APIs that have the one-to-one relationship do not work when the FKs do not exist in the record. I am getting the following error message in the query response.

{
  "name": "AdapterError",
  "adapterMethodName": "find",
  "modelIdentity": "menu",
  "raw": {}
}

and error message on the debug log:

error: Sending 500 ("Server Error") response:
 AdapterError: Unexpected error from database adapter: Cannot read property 'undefined' of undefined

The sample model that I defined is the following:

attributes: {    
"name": {
  type: "json"
},
"description": {
  type: "json"
},
"horizontalImageURL": {
  type: "string"
},
"verticalImageURL": {
  type: "string"
},
"currency": {
  type: "string",
  isIn: ["GBP", "EUR", "CNY"],
  defaultsTo: "GBP"
},
"price": {
  type: "number",
  defaultsTo: 0.00,
},
"menu": {
  model: "Menu",
  unique: true
},
"discount": {
  model: "Discount"
},
"image": {
  model: "Image"
},
"commission": {
  type: "number",
  defaultsTo: 0.00,
},
"commission_type": {
  type: "string",
  isIn: ['fixed-amount', 'percentage']
},
"stock": {
  type: 'number'
},
"paymentProvider": {
  type: 'string',
  isIn: ['wirecard', 'stripe', 'wechat']
},
"isReservationRequired": {
  type: 'boolean'
},
"maxParty": {
  type: 'number'
}}

I followed the example from http://next.sailsjs.com/documentation/concepts/models-and-orm/associations/one-to-one but still able to solve the issue. Any advice on solving this blueprint issue on Sails v1 will be great.
