• Can you do a little debugging first and e to us with an actual question? Maybe show what you've tried? – evolutionxbox Commented Jan 16, 2017 at 14:54
• expecting type is string for which you got response as object. – Jyothi Babu Araja Commented Jan 16, 2017 at 14:56

I think that {} is not a valid default for the 'post' member.

post: {type: String, default:{}},

Either the 'post' default value should be a string and you need to provide one, or an empty object, and then the type should not be "String".

Take a look at my response in this other related question. The same applies for 'reserved mongoose words' such as 'type' and 'value':
