[expo-51] Android app unable to resolve module expo-router/entry inside monorepo (new arch enabled or not) about expo HOT 2 OPEN

Hi @sync! Thanks for reporting this issue. Monorepos are hard, and the resolving logic in Metro isn't helping here at all. Eventhough I can't seem to reproduce this exact issue in your repository, one way this might be fixed (besides the EXPO_USE_METRO_WORKSPACE_ROOT=1) is this:

• Create your own entryfile, e.g. apps/borg/index.ts
• Only add import 'expo-router/entry'; in this entry file
• Change apps/borg/package.json main to index.ts.

This is because Metro might not play nice with a combination of entry points from node_modules and monorepos. I do the exact same thing in my monorepo example here.

Hope this helps!

EXPO_USE_METRO_WORKSPACE_ROOT=1 in a .env or before the start command fixes it, I guess it is required ?
