When running in cluster mode, passing references does not work, e.g.,:

auto r3 = Ray::Task(Return1).Remote();
auto r4 = Ray::Task(Plus1, r3).Remote(); // passing r3 as reference argument

• I have verified my script runs in a clean environment and reproduces the issue.
• I have verified the issue also occurs with the [latest wheels](https://docs.ray.io/en

This could be a good place to start.

1. Star it
2. Fork the repo
3. Clone it onto your PC.
4. Create a folder with your GitHub username
5. Create separate files for all the issues you are solving and always open an issue which has all details of the process or method you will use to perform anomaly detection and wait till it is assigned (not more than 2-3 hours it will take, we are passionate open source developers )
6. Open PRs
