I'm really sorry. I broke this when I merged the conflict that I created in package.json with CI updates.
I did this

"serve:storybook": "yarn --cwd storybook storybook"

But that does not work. Can you put it back almost the way you had it originally.

"serve:storybook": "cd ./storybook && yarn run serve"

sorry! :-(

I figured out I could fix my own mistake. :-)
