Hi kfn8dkodemonkey , unfortunately I wasn't able to fix it even after cloning the repo

code snippet: const { GraphQLServer, PubSub } = require("graphql-yoga"); const pubSub = new PubSub();

Hi Victoria. First of all thanks, I love the content. I understand we are implementing this code all in the index js file. However (pardon my ignorance I'm still a newbie) I'm getting the below error message. I'm having a hard time debugging. Any assistance is greatly appreciated. TypeError: PubSub is not a constructor at Object.<anonymous> (C:\Users\K-Von\Desktop\projects\github-help\project\server\index.js:4:16)
