ACTIVE RECORD ERROR: Couldn't find Customer with 'id'=1 [WHERE (`customers`.`company_id` IS NOT NULL) AND `customers`.`company_id` = ?] RUBY ON RAILS

Im running RSPEC tests on my Ruby on Rails Controller, here is the controller action I am testing:

CONTROLLER CODE:

class Customers::AccountsController < ApplicationController
   before_action :set_customer

    def index
      @accounts = @customer.accounts
      respond_to do |format|
        format.html
        format.json
    end

  def set_customer
      @customer = current_member.company.customers.find(params[:customer_id])
  end

Here is my RSPEC Test Code:

 before do
    @member = FactoryGirl.create(:member)
    @company = FactoryGirl.create(:company, owner_id: @member.id) 
    @customer=FactoryGirl.create(:customer_john_human,company_id:@company.id)
  end

 describe "GET INDEX" do 
    it "gets the index html page" do 
    get :index, {:customer_id=>@customer.id, :format=>:json}
    end
 end

THE ERROR:

ActiveRecord::RecordNotFound:
Couldn't find Customer with 'id'=1 [WHERE (`customers`.`company_id` IS NOT NULL)   AND `customers`.`company_id` = ?]
    # ./app/controllers/customers/accounts_controller.rb:87:in `set_customer'
    # ./spec/support/engine_controller.rb:25:in `process_action'
    # ./spec/support/engine_controller.rb:3:in `get'
    # ./spec/controllers/customers/accounts_controller_spec.rb:21:in `block (3 levels) in <top (required)>'

I am unsure what 'customer.company_id = ?' means, - if i do :

puts @customer.inspect

i get the following output:

#<Customer id: 2, user_id: nil, title: nil, first_name: "John", last_name: "Kusu", created_at: "2015-04-27 18:42:00", updated_at: "2015-04-27 18:42:00", deleted_at: nil, company_name: nil, company_id: 6>

As far as i can tell, company_id is defined and set as 6. I am not sure why I am getting this error?
