Unexpected '<' error for post while using Postman and rails

Question

My JSON response to be populated is as follows:

{
    "vendor":
    {
     "name": "Mozelle Luettgen MD",
     "email": "[email protected]",
     "phone_no": "9999997660",
     "addressline1": "Kulas Stravenue",
     "addressline2": "64636 Lynch Springs",
     "landmark": "Apt. 142",
     "city": "South Hannaview",
     "state": "North Dakota",
     "country": "Palau",
     "pincode": "53912-6122",
     "latitude": 50.8247548421224,
     "longitude": -81.8429583068792,
     "status": true
    } 
 }

My controller code for create vendor is

  def create 
    @vendor = Vendor.new(vendor_params)
    respond_to do |format|
    if @vendor.save
      format.html { redirect_to @vendor, notice: 'Vendor was                         
      successfully created.' }
      format.json { render :show, status: :created, location: @vendor, 
      :msg => { :status => "ok" , :result => @vendor.json, :message =>  
      "Succesfully Created" }
      }
    else
     format.html { render :new }
     format.json { render json: @vendor.errors, status: 
     :unprocessable_entity, 
     :msg =>
     { :status => "Error", :message =>  "Unprocessable Entity" }
     }
   end
  end
end


  def vendor_params
  params.require(:vendor).permit(:name, :email, :phone_no,
     :addressline1, :addressline2, :landmark, 
    :city, :state, :country, :pincode, :latitude, :longitude, :status, 
    {products_attributes: [:id, :product_name, :price]},
    {vendor_products_attributes: [:id, :vendor_product_id, :vendor_id,             
   :product_id, :copies, :_destroy]})
end

While running this link http://localhost:3000/vendors/create_vendor with post, the status shows 200 ok, but when I look for the JSON response,for the created vendor, it throws Unexpected '<' error.What am I doing wrong.Can someone please elaborate

Answer 1

I had the same issue and was able to get it sorted by changing the syncing link

Answer 2

Make sure you do not have declared twice this var User=require('../Models/user'); object of model class both in route/user.js and main server/app.js file

You declared object two times of model class

Answer 3

This Setting in postman application helped me to resolve this problem

Global Proxy Configuration:ON

Proxy Type: HTTPS

Proxy Server: abc.xyz.abc.com:8080

Use System Proxy: OFF

Answer 4

The reason is that you might have opened the session by logging into another browser or some where else while trying to connect to postman. That is the reason you are getting "unexpected '>'".

To avoid that, login to postman with the login api and try to hit your service. It will work for sure.
