Hello, I am using Ruby 2.4.10, Rails 5 on WSL. I recently ran bundle update and now I get this error in rails when running ./bin/webpack-dev-server. If I don't run the dev webpack server, rails compiles it on its own fine, but it takes a long time. The reason I am posting here is because it seems the stack trace points to an error in the rack-proxy module.
