Sandpack doesn't resolve react@19.2.0, breaking the React website

[gaearon]

See reactjs/react.dev#8037.

React 19.2.0 is released but Sandpack refuses to resolve it.

Opening sandboxes in a new tab works fine.

Has it cached a 404 for the package version or something like that?

@CompuIves @alexnm @sannek Any chance someone might be able to have a look? We've plugged the urgent fix but now the website is using a canary which is weird.

To repro, you can open any sandbox in React docs on this branch: reactjs/react.dev#8037

It says Cannot find module 'react' from '/src/index.js' which doesn't make sense. And it doesn't seem to resolve 19.2.

The https://sandpack-cdn-staging.blazingly.io/dep_tree/NSh7ImNvcmUtanMiOiIzLjIyLjciLCJyZWFjdCI6IjE5LjIuMCIsInJlYWN0LWRvbSI6IjE5LjIuMCIsInJlYWN0LXJlZnJlc2giOiJeMC4xMS4wIn0p response is wrong, it doesn't include react and react-dom at all despite them being requested. Also asking for latest gives us 19.1.0.

Filed codesandbox/sandpack-cdn#43 which is probably more correct repo
