From Discord: V8 Cloning Errors in Electron with Fiber-Passed Objects

Open effect-bot opened this issue 5 months ago • 0 comments

Summary

Summary:

  • Issue: The user is experiencing V8 cloning errors in Electron when objects returned by a Fiber are passed through serialization code. These objects are plain objects, but they can't be cloned.
  • Possible Cause: The user suspects that Effect.fail(serializableValue) might be returning a proxy object instead of a plain object.
  • Confirmation: Michael Arnaldi confirms that Effect.fail does indeed create a proxy to attach the stack trace.
  • Solution: Michael suggests that the original instance can be restored to avoid the cloning issue.
  • Additional Context: Michael mentions that in prior versions, the stack trace was attached to the Cause, but it was lost when re-raising an error, leading to the current proxy approach. He also notes that this behavior should be documented.

Key Takeaways:

  1. Effect.fail and Proxies: Effect.fail creates a proxy object to attach stack traces, which can cause issues with object serialization in environments like Electron.
  2. Restoring Original Instances: There is a way to restore the original instance from the proxy to avoid serialization issues.
  3. Documentation: The behavior of Effect.fail creating proxies for stack traces should be documented to help developers understand and troubleshoot similar issues.
  4. Edge Cases: This issue is considered an edge case but is important for developers working with serialization and error handling in complex environments.
