JSON::ParserError: unexpected token at '' on Rails Rspec - ruby-on-rails

Question

I'm quite having an issue on my Rspec. So basically what I want is to send a request to the API, and have a proper response. When I send the data to the API endpoint, and I puts what it sends, it looks like it sends all the data correctly, but at the response level, it says that I am not sending the required parameters. (I am also using VCR to test)
My RSPEC:
require 'rails_helper'
describe 'Create Vendor', type: :request do
let(:user) { create(:alter_user) }
let(:vendor_attributes) do
{
#These are all the required parameters
vendor: {
token: '',
refcode: '',
request_type: 'renters',
first_name: 'Tony',
last_name: 'Stark',
phone: '6504881234',
phone_type: 'mobile',
email: 'tony#starkindustries.com',
address1: '123 Main Street',
address_city: 'Palo Alto',
address_state: 'CA',
address_zip: '94301',
DOB: '1982-10-27'
}
}
end
after do
VCR.eject_cassette
end
it 'creates a vendor' do
VCR.use_cassette('create_vendor') do
post '/api/v2/vendor', params: vendor_attributes.to_json, headers: {'Content-Type' => 'application/json', Authorization: "Token token=#{user.key}"}
response_body = JSON.parse(response.body)
expect(response_body['refcode']).to eq('corp-api-test')
end
end
it 'fails if the vendor is missing attributes' do
VCR.use_cassette('create_vendor_missing_attributes') do
post '/api/v2/vendor', params: {vendor: {last_name: 'Stark', phone: '6504881234'}}.to_json, headers: {'Content-Type' => 'application/json', Authorization: "Token token=#{user.key}"}
expect(response.status).to eq(422)
end
end
it 'requires Authorization token header' do
post '/api/v2/vendor', params: vendor_attributes.to_json, headers: {'Content-Type' => 'application/json'}
expect(response.status).to eq(401)
end
end
When I execute the rspec filePath I receive this:

This is my vendor controller
As you can see here I print what I send to the API, it sends the data but then it fails to create a vendor.
def corp_new_vendor_v2
arguments = create_vendor_arguments
https = Net::HTTP.new(VENDOR_CREATE_VENDOR_URI.host, VENDOR_CREATE_VENDOR_URI.port)
https.use_ssl = true
post_request = Net::HTTP::Post.new(VENDOR_CREATE_VENDOR_URI)
post_request['Content-Type'] = 'application/json'
post_request.body = JSON.dump(arguments)
print "Post Request----: #{post_request.body}\n\n"
print "-----------------------------------------------------\n"
response = JSON.parse(https.request(post_request).read_body).symbolize_keys
print "Response----: #{response}\n\n"
print "-----------------------------------------------------\n"
if response[:result] == 'success'
puts 'It was successful'
else
render json: { error: response[:message] }, status: :unprocessable_entity
end
end
# This is used once we touch the new vendor endpoint, and response with a response
def create_vendor_attributes(response)
response.slice(:action, :user_hash, :result, :vendor_uuid, :policy_shell_uuids, :refcode, :return_URL)
end
def create_vendor_params
params.require(:vendor).permit(
:request_type, :first_name, :last_name, :phone, :phone_type, :email, :address1, :address_city, :address_state, :address_zip, :DOB
)
end
def create_vendor_arguments
create_vendor_params.to_h.merge(token: CORP_RENTER_TOKEN, refcode: CORP_REFCODE)
end
end
What am I missing here? On my spec I'm sending everything but I keep receiving the par JSON error.
I will appreciate the help!

Answer 1

You are missing the render :json for the success.
Update your controller with the following
if response[:result] == 'success'
render json: response, status: :ok
else
render json: { error: response[:message] }, status: :unprocessable_entity
end
