Why is react-dom imported in my bundle even though it isn't a depedency

[hmbrg]

Hey,

I'm creating a react-native library using tsdx and I have the following problem:

My dist imports import 'react-dom'; at the top of the file even though it's not a dependency anywhere. I can't figure out how to remove it.

When executing yarn analyze I even get an error saying that react-dom can' be resolved.

My package.json looks like this:

Thanks so much for the help in advance!
I've been stuck on this issue for hours.
