Error in getNode while accessing symlink

[rmartins90]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch @electron/[email protected] for the project I'm working on.

Here's the error I was having, it happened while accessing symlink in macOS library.

Here is the diff that solved my problem:
