Lingo.dev compiler fails with “TypeError: traverse is not a function” in React Router v7 + Vite

What's happening?

First of all, thanks for the awesome project!

I’m running into an issue when using React Router v7+ with Vite.
When starting the development server, the Lingo.dev compiler fails during localization.

Exact Reproduction Steps

1. Created an empty react router project
2. Config
3. Run

I'm getting the same error in the same setup.

It is not happening on version 0.115.0, but start happening on 0.116.1 and later.

It seems fixed in 0.117.1 😄
