Passing bearer token in RSPEC (no implicit conversion of nil into String)

require 'rails_helper'
RSpec.describe "User management", :type => :request do
    describe "PeopleGoal::V2::Users" do
        describe "GET /api/v2/users/" do

          it 'returns status 200, authorized' do
              @token =  "Bearer 123"
              @url = "https://api.peoplegoal-v2.com/v2/users/me"
              @headers = { "AUTHORIZATION" => @token}
              get @url, as: :json, headers: {:Authorization => @token}
              expect(response.status).to eq 200
          end
        end
    end
end

I am trying to pass the @token but I am getting this error

 Failure/Error: get @url, as: :json, headers: {:Authorization => @token}

     TypeError: no implicit conversion of nil into String

I can make a get request without the params and headers and it works but as soon as I add params or headers I get the error, I even tried writing it like so

1 - get @url, {}, { Authorization:  @token} 
ArgumentError: wrong number of arguments (given 2, expected 1)

2 - get @url, params: {}, headers: { Authorization:  @token}
TypeError: no implicit conversion of nil into String

Some smart people please point me in the right direction =).
