I am creating an react-native application in VSCode and am receiving an error when trying to run the application in the iOS Xcode simulator. I had a perfectly working version of the application in chrome localhost, but since transferring the file over to a react-native project that includes the iOS and android files, I keep receiving this error. I have tried other online solutions dealing with storybook but still have had no luck. I will attach my package.json file. Anything helps. Thanks Package.json Error Recieved

Error Received on Xcode Simulator:
