When I run the following line trying to build a non Expo React Native app for iOS using EAS Build I get an error “Could not find target with id ‘undefined’ in project.pbxproj”. I’m sure it’s just a config error, but I’m not sure where the ‘undefined’ is pulling from. Any help would be greatly appreciated.

eas build --platform ios --profile staging

The response I get is as follows:

Loaded "env" configuration for the "staging" profile: REACT_APP_ENVIRONMENT, RECEIPT_URL_STAGE, RECEIPT_URL_PROD, NO_FLIPPER, APP_IDENTIFIER, EXPIRED_COOKIE. Learn more: https://docs.expo.dev/build-reference/variables/
