AppDynamics Native Agent Not Loading with Nexe-bundled NodeJS Application

Environment
- Node.js version: 20.9.0
- AppDynamics Node.js Agent version: Latest
- Nexe version: Latest
- OS: Windows Server
- Build tool: Nexe with custom build script

Project Structure
We have a Node.js API service that uses:
- Express.js for REST API
- Native modules (specifically AppDynamics agent)
- Various npm packages for business logic
- Built and distributed as a single executable using Nexe

 

Issue
When running our Nexe-bundled application, the AppDynamics agent fails to initialize with the following error:

 

Appdynamics agent cannot be initialized due to Error: Missing required module. \\?\C:\Path\nodejs_api\node_modules\appdynamics-libagent-napi\appd_libagent.node TypeError: Cannot read properties of undefined (reading 'init') at LibagentConnector.init


What We've Tried
1. Including the native module as a resource in Nexe build:
--resource "./node_modules/appdynamics-libagent-napi/appd_libagent.node"

2. Copying the native module to the correct directory structure in distribution:

dist/

- api_node.exe

- node_modules/

-- appdynamics-libagent-napi/

--- appd_libagent.node

 

According to Nexe's documentation, when dealing with native modules (.node files), the module should be placed in the `node_modules` directory relative to the compiled executable's location. This means that while the application is bundled into a single executable, native modules are expected to be loaded from the filesystem at runtime.


Question
How can we properly bundle and load the AppDynamics native agent with a Nexe-compiled Node.js application? Is there a specific configuration or approach needed for native modules, particularly AppDynamics, to work with Nexe?

Any guidance or working examples would be greatly appreciated.
