Conversation
Three bugs in pact 2.0.0 require host-app workarounds until upstream fixes land: 1. Missing activesupport dependency (present?/blank? used internally) 2. rack-proxy 0.7.7 calls body_stream.rewind on Rackup::Handler::WEBrick::Input which lacks the method under rackup 2 / rack 3 3. WebmockHelpers.turned_off missing return before early yield, falls through to WebMock::Config when WebMock is not defined Adds a "Known Issues and Workarounds" section with individual fixes and a combined pact_helper.rb snippet.
