Error when using latest create-react-app

Describe the bug
I recently updated @storybook/react and react-scripts, and now I cannot start storybook.
With @storybook/react@5.2.1 and react-scripts@3.1.x, I get the error presented on the screenshot. Changing back to react-scripts@3.0.1 though works fine.

To Reproduce
Steps to reproduce the behavior:

1. Install @storybook/react@5.2.1 and react-scripts@3.1.x,
2. Create a story
3. Start storybook
4. See error

Expected behavior
Should not crash.

Having the same issue.
As stated, downgrading react-scripts to 3.0.1 works

Hi @0tho, have you tried (while on the newer react-scripts) removing your node_modules and lockfile, and reinstalling?

[calumgunn]

Hi @mrmckeb - I'm having the same issue, and a reinstall didn't fix things.

My error is different, however:

Uncaught (in promise) TypeError: Cannot convert undefined or null to object
    at Function.entries (<anonymous>)
    at vendors~main.cff839a2a50bbfd2c813.bundle.js:8101
    at memoizerific (vendors~main.cff839a2a50bbfd2c813.bundle.js:67932)
    ...

Do let me know if this feels separate to this issue and I'll add a new one!

[mrmckeb]

Are you able to share that repo with me @calumgunn?

[calumgunn]

@mrmckeb Sadly not as it's in a private repo... I'll try to find time to create a minimal reproduction today.

[marcel0ll]

@mrmckeb deleting node_modules, lockfile and reinstalling didn't solve the problem. (tried both npm and yarn)

I also can't share my main repo, but I will try to create a minimum project later.

I believe this error could be related to this

[mrmckeb]

Thanks, reproductions are very valuable - and I understand that you can't always share a project.

@0tho, if you're issue is related to the issue you linked to, that has been resolved... I'll ask for a patch release.

@mrmckeb updated to react-scripts@3.1.2 and for me it has fixed the problems.
