# Bug Report: Dependency Conflict with customerio-reactnative

[Valentin-Gaudin]

SDK version

• Customer.io SDK: ^3.9.1
• Expo SDK: 52

Environment

• Environment: Development (EAS Build)

Are logs available?

No logs are currently available, but the following error is encountered during the eas build process:

[!] There are multiple dependencies with different sources for customerio-reactnative in Podfile:
	•	customerio-reactnative (from ../node_modules/customerio-reactnative)
	•	customerio-reactnative/apn (from ../../node_modules/customerio-reactnative)

Describe the bug

When running the eas build command, the build fails due to conflicting dependencies for customerio-reactnative in the Podfile. The error suggests that the library is being referenced twice with different paths:

1. ../node_modules/customerio-reactnative
2. ../../node_modules/customerio-reactnative/apn.

This appears to be caused by incorrect path resolution in a monorepo workspace structure.

To Reproduce

Appears in expo build online

1. Project setup:
   • Monorepo workspace with a native folder for builds.
   • Shared node_modules directory.
2. Install dependencies using Yarn or npm.
3. Run the following command to build:

eas build -p ios --profile development

Expected behavior

The build should complete without dependency resolution errors.

Screenshots

Additional context

Project configuration: Monorepo using Expo and React Native.
Structure: The native folder contains generated native code (iOS/Android), and dependencies are declared in a shared workspace.

Thanks for the detailed report!

I'd like to confirm a few things to be able to better help with the issue:

• You are using our Expo plugin with your app? (This repo is for vanilla ReactNative SDK without Expo)
• In your monorepo setup do customerio-expo-plugin and customerio-reactnative live in different node_modules directories?
• Can you elaborate on the structure of your project and how is CIO Expo plugin is added as a dependency and configured? Attaching CIO Expo, CIO RN SDK and Expo versions would be helpful.
• Attaching the generated Podfile could be help as well

We don't have explicit support for monorepos with our Expo plugin so if in fact customerio-expo-plugin and customerio-reactnative do reside in the same node_modules directory, that could be causing the issue.

If you are not comfortable sharing any of the information here, feel free to contact us through [email protected] and mention this ticket number.

You’r welcome !

• Yes i use the customerio-expo-plugin in the app with this latest release : 4.1.1
• They are not leaving in different directories, just in native folder
• The project are living in this way :
