Title:
[Bug]: UnusedModuleInterfaceParserError in NativeClerkModule during Android build (Expo SDK 55 / New Architecture)
Environment:
- OS: Windows
- Package Manager: Bun
- Node Version: 25.2.1
- Expo SDK: 55.0.0
- @clerk/clerk-expo Version: (Latest)
Description:
When trying to build the Android development client using the New Architecture / Codegen, the build completely fails at the :clerk_expo:generateCodegenSchemaFromJavaScript task.
React Native's Codegen is throwing an UnusedModuleInterfaceParserError because it finds an unused Spec interface inside NativeClerkModule.ts. It looks like the module is missing the TurboModuleRegistry.getEnforcing<Spec>('NativeClerkModule') export at the bottom of the file.
Note: I see there is a recent PR (#8112) that seems to address this, but the issue is currently blocking Android builds in production/development on the latest published version.
Steps to Reproduce:
- Initialize an Expo SDK 55 project with
@clerk/clerk-expo. - Run the Android build with Bun:
bunx expo run:android - The build fails during the
Configure project :expo-modules-corephase.
Error Logs:

[expo-max-sdk-override-plugin] This plugin will find all permissions declared with `android:maxSdkVersion`. If there exists a declaration with the `android:maxSdkVersion` annotation and another one without, the plugin will remove the annotation from the final merged manifest.
