Selective hydration internal React error leaked to userspace
This is not a real error. It's an implementation detail of React's selective hydration feature. If this leaks into userspace, it's a bug in React. Please file an issue.
React marks this as an internal error that should not normally surface to application users. If you see it, the problem is often a framework integration issue, a miscompiled React bundle, or a bug worth reducing and reporting.

Why it happens
An internal selective-hydration implementation detail leaked out through a framework or bundler integration path.
React or React DOM versions are mismatched or bundled incorrectly.
A framework-level SSR or hydration integration bug surfaced an internal React invariant.
How to fix it
Make sure `react` and `react-dom` are on compatible versions and are installed only once in the app.
Check for framework, bundler, or runtime integration issues if the error appears during SSR or hydration.
Reduce the issue to a minimal reproduction and report it if it persists, since React marks this as an internal bug path rather than expected app behavior.
Try upgrading React and the host framework if the error began after a partial package update or custom runtime change.
