Working with monorepos, using local modules, and using 'eas build' leads to a 'Not found' error. about expo

[brentvatne]

hi there,

• you appear to be using both npm and yarn - your repo has a package-lock.json and yarn.lock. if you follow the instructions from the monorepos guide this will indeed work.
• this is not actually called "autolinking" - this refers to linking of native packages.
• here is an example you can try initializing from / comparing yours to: https://github.com/expo/examples/tree/master/with-yarn-workspaces

[Mfweb]

• linking of native packages

This example doesn't work.
I created a project using npx create-react-native-app --template with-yarn-workspaces without making any changes, then compiled it with eas build --platform android --profile production, but it still gives an error:

Welcome to Gradle 8.6!
Here are the highlights of this release:
- Configurable encryption key for configuration cache
 - Build init improvements
 - Build authoring improvements
For more details see https://docs.gradle.org/8.6/release-notes.html
To honour the JVM settings for this build a single-use Daemon process will be forked. For more on this, please refer to https://docs.gradle.org/8.6/userguide/gradle_daemon.html#sec:disabling_the_daemon in the Gradle documentation.
Daemon will be stopped at the end of the build

@Mfweb - you need to add a step to run yarn build in expo-custom directory, eg:
