Cannot restore point because saved chunk is no longer connec

Error message

Cannot restore point because saved chunk is no longer connected to root

What it means

Internal invariant of slate-react's chunk tree helper: restorePointer() could not find a path from the saved chunk back to the root, meaning the chunk was detached from the tree between savePointer() and restorePointer(). Marked 'istanbul ignore next' — an internal bug, not caller error.

    // pointer since it was saved, the index and index stack must be
    // recomputed. This is slow, but this is fine since restoring a pointer is
    // not a frequent operation.

    const { chunk, node } = savedPointer
    const index = chunk.children.indexOf(node)

    // istanbul ignore next
    if (index === -1) {
      throw new Error(
        'Cannot restore point because saved node is no longer in saved chunk'
      )

Solutions

1. Update slate-react
2. Report a minimal reproduction to the Slate maintainers
3. Refrain from mutating internal chunk structures in forks

try {
  applyOperations()
} catch (e) {
  if (e.message.includes('no longer connected to root')) {
    // internal bug: fall back to a full re-render / remount
  } else throw e
}

When it happens

Trigger: Internal bug where insertAfter detaches the saved chunk before restoring the pointer; unreachable through documented APIs.

Common situations: Slate-react chunking bugs on very large documents; fork modifications that reparent chunks.
