Troubleshooting using the http resource on an Azure load balancer

Backtrace

inspec/lib/resources/http.rb

def body
  @worker.body
end

When running the http resource locally, @worker is set properly. When running the http resource on an Azure load balancer, @worker is set to nil.

This is where that error is being generated - in the instance_eval method
inspec/lib/inspec/rule.rb

     begin
        instance_eval(&block)
      rescue StandardError => e
        # We've encountered an exception while trying to eval the code inside the
        # control block. We need to prevent the exception from bubbling up, and
        # fail the control. Controls are failed by having a failed resource within
        # them; but since our control block is unsafe (and opaque) to us, let's
        # make a dummy and fail that.
        location = block.source_location.compact.join(':')
        describe 'Control Source Code Error' do
          # Rubocop thinks we are raising an exception - we're actually calling RSpec's fail()
          its(location) { fail e.message } # rubocop: disable Style/SignalException
      end
