Getting error on tests when using @rnx-kit/babel-preset-metro-react-native

[JerryMacedoCastro]

What happened?

My react-native app asks for a babel plugin when I run the unit tests. I guess one goal of rnx-kit is no need several things installed in order to your app works.

Here is the error message:

Hi @JerryMacedoCastro, can you share a link to your repository so I can reproduce the issue and see what is going on? Or, if you're working in a private repository, can you create a new one public repo which shows off the problem?

[JerryMacedoCastro]

I'll try to create a public repo and reproduce the problem!

I created the repo with the same configuration but the erros doesn't occurs. Here is the link https://github.com/JerryMacedoCastro/rnxkitexample

I'm working with yarn workspaces I don't if this can be related.

Hmmm... Without a reproduction of the error, there's not much I can do to help. Sorry.
