EAS Build Unable to find a specification for `React-RCTAppDelegate` depended upon by `ExpoModulesCore`

Managed workflow
eas-cli/3.3.2 darwin-arm64 node-v19.1.0

A bit more context: this is running in a yarn monorepo, and I’ve followed the expo monorepo set up page. Note: this works locally with expo run:ios

I’ve tried reinstalling my packages, running expo doctor, but nothing seems to be working.

it’s likely because I’m using yarn 3
is it possible to let EAS run with yarn 3 instead of yarn 1?
