Using react-scripts 4.0.0 breaks storybook-build fails at 92% of build process on chunk asset optimization TerserPlugin

[jessepinuelas]

Describe the bug
No longer able to build after updating to react-scripts 4.0.1 Previously I was able to simply run npm run build-storybook. Now when running the build command it fails. It fails at 92% of build process on chunk asset optimization TerserPlugin.

To Reproduce
Use a version of react-scripts below 4.0.0 for example 3.4.4 running build-storybook will work
Install reacts-scripts 4.0.1 running build-storybook will fail

Expected behavior
Successfully builds storybook

Did you solve this?

not related to CRA but found after upgrading to 6.3.2 terser was breaking CI pipeline (see here setting minimize to false solved it for now)

this actually still happens with storybook 6.4.22
