undefined is not a function- Error in Sails

Question

I am facing the following error in Sails when I run sails lift which is as follows

usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/util /schema.js:59
attributes[key].type = attributes[key].type.toLowerCase();                                                  
TypeError: undefined is not a function

My model has the following attributes

SerialNo: {
  type: 'integer',
  unique: true,
  required: true,
  index: true
},

CreatedAt: {
  type: Date,
  default: Date.now
}

I don't understand the error. I have no functions in the corresponding controller. I also have not defined any routes as of now.

Can somebody help me with this error?

You don't have to use a createdAt attribute which exists implicitly — Yann Bertrand
The Date type doesn't exist in Waterline, you'll have to use type: 'datetime' — Yann Bertrand
The default attribute option doesn't exist. You can use defaultsTo — Yann Bertrand
@YannBertrand. I did Type 'datetime ' and it worked for for me. Also when I did type='date', I still got output. Can you tell is there an difference between the two. — shubhamagiwal92

in Your Model you have to change your model like this :

SerialNo: {
  type: 'integer',
  unique: true,
  required: true,
  index: true
},

CreatedAt: {
  type: 'Date',
  default: Date.now
}

note : in sails type must have this ' '
