Describe the bug

I was trying to see if the @next version had fixed this issue:

but instead I got:

To Reproduce

I've updated my packages from ~6.1.21 to ~6.2.0-beta.14
Do I need to update something in my webpack config or something?

Additional context

I've removed my custom panel and my 6.1 installation seems to not work with 6.2 🤔

[shilman]

Did you try removing node_modules and/or lockfiles and reinstalling?

[matheo]

@shilman yep, I doubled checked and I did refresh the node_modules when updating it :)

[ayhid]

I have the same issue with 6.2.7 :/ @matheo did you solve the problem ?

[matheo]

Nope, I'm still waiting a deep solution :(
cc @shilman

[shilman]

Do you have a repro repo you can share?

[carlosbaraza]

I'm getting this error too. It happens intermittently, sometimes when I change the main.js or preview.js it will start appearing. And sometimes it will just work, which makes it quite strange.

[carlosbaraza]

Not sure if this has fixed it. But I updated react to 17.0.2 (was on 17.0.1) and react-dom, and now it seems to be stable 🤞

[matheo]

Thanks for the tip @carlosbaraza !

[matheo]

Didn't work for my repo 😞
(I see that @storbook/angular relies on react@16.14 but I guess it doesn't affect the manager, dunno)

[shilman]

@matheo that dep is for the manager. we can try updating it in 6.3 and see if that fixes your problem?

[matheo]

yes please @shilman 🙂

[evelynhathaway]

Data point: We were already on react and react-dom v17, but upgrading to the v6.3.0 storybook beta and downgrading back to stable worked. Possibly it was an issue with our cached manager or node module resolutions.

[matheo]

@shilman I've upgraded to @storybook/angular@6.3.0-beta.4 and it still uses react-dom@16.14.0 therefore I have no way to confirm that the exception comes from that one, I still have it :(

[gavmck]

I had some conflicting versions of react which I'm not sure contributed to this. I ended up having to delete my package-lock.json and node_modules folder and re-run npm install.

The error initially surfaced during a mass upgrade of dependencies to try and bring things up to date.

[matheo]

I finally found a solution while upgrading to Storybook v6.3.9!
To fix my package.json to React v16:

    "react": "16.14.0",
    "react-is": "16.13.1",

I am also getting this error, I tried using React 17.0.2 and 16.14.0 but still getting the Scroller error.

[ChazUK]

Sorry, nuked my node_modules folder and switch to 16.14.0 and it's now working!

[Pringels]

I have the same issue. (@storybook/preact: ^6.3.12, Preact 10.5.14)

Tried nuking node_modules and lockfiles but nothing works.

Update: If I remove @storybook/addon-postcss it works again.

Update 2: Adding @storybook/addon-postcss back and switching to v6.4.0-beta.28 fixes the issue.
