Gatsby doesn't work with React 17 RC (Error: React-Hot-Loader: AppContainer should be patched)

See original GitHub issue

Update react and react-dom to 17.0.0-rc.1
Update gatsby to latest
Run yarn dev

This is the result:

While there’s ongoing work to make Fast Refresh the default for compatible setups, in the meantime, can we figure out how to fix this error?

I’m guessing that what needs to happen is for https://github.com/hot-loader/react-dom/issues/41 to be solved by publishing a patched package. This is likely little work, but requires access to that package (cc @theKashey). I could do this myself if I had the instructions.

Concretely, if you’re running this error, the fix is to run npm update.

If this didn’t help, delete your lockfile (yarn.lock or package-lock.json) and re-run your package manager.

hot-loader/react-dom(17.0.0-rc.2) and react-hot-loader(4.13.0) were updated and should not cause the issue anymore.
