"Error: .sourceMap is an alias for .sourceMaps, cannot use both" on Storybook start, RN 0.56

[todorone]

Bug or support request summary

The mobile application starts correctly, but the web part throws an error and stays blank. I guess it's somehow related to babel 6 -> 7 transition, but although I tried all workarounds, nothing did help...

Steps to reproduce

Running yarn storybook results in:

yarn run v1.9.2
$ storybook start -p 7007
=> Loading custom .babelrc from project directory.
=> Loading custom addons config.
=> Using default webpack setup based on "Create React App".
Scanning folders for symlinks in /Users/fedirushakov/Documents/phyzeek-mobile/node_modules (20ms)

React Native Storybook started on => http://localhost:7007/

I'm seeing the same 👍 . I think it has to do with the babel preset, because if I revert just the react-native dependency, it still fails with this message
