Summary

The Server Functions documentation page is broken and crashes when loaded.

Page

https://react.dev/reference/rsc/server-functions

Details

When I visit the Server Functions documentation page (https://react.dev/reference/rsc/server-functions), the page crashes instead of loading correctly.

I've attached screenshots showing the issue.

I can reproduce this issue as well.

Environment:
OS: Windows 10
Browsers: Google Chrome and Microsoft Edge
Location: India

I also tried:
Incognito mode
Hard refresh
Disabling cache in DevTools

None of these resolved the issue.

Console output:
Minified React error #419
The server could not finish this Suspense boundary, likely due to an error during server rendering. Switched to client rendering.
Error: Could not find: 'submitAction'

Other pages on react.dev work normally. Only https://react.dev/reference/rsc/server-functions is affected.
