Hello. I am having issues understanding an error

Cannot read properties of undefined (reading 'secondary')

You can see it live for yourself here:

Any lead will be appreciated
Thanks 👍

Anyone has a clue ?

This can happen when there are mixed versions of storybook packages. Can you share the output of npx sb info?

Definitely

That seems fine, but you may still have an outdated version hiding somewhere in your lockfile. I'd recommend trying to delete your lockfile and node_modules directory, then re-install, and see if that changes anything.

If that doesn't fix it, then my theory is wrong.

The other possibility is that scss is not being compiled correctly

I don't use scss personally, though. Does it render fine if you remove the Secondary story?
