Cannot get the parent of path [${path}] because it does not

Error message

Cannot get the parent of path [${path}] because it does not exist in the root.

What it means

Node.parent() computes the parent path via Path.parent and resolves it; if that resolution lands on a Text node, the requested path cannot exist (text nodes have no children), so the path itself is invalid. The message says the path 'does not exist in the root' because descending past a text node is impossible.

Solutions

Verify the path exists first with Node.has(root, path) before asking for its parent.
Re-derive the path from the current tree (selection, Editor.nodes) instead of reusing cached paths across mutations.
If you only need the parent path (not the node), use Path.parent(path) directly — it only throws on the root path [] and never does node lookups.
During heavy transforms, wrap lookups and retry after the document settles (post-normalization).

Example fix

// before
const parent = Node.parent(editor, path)

// after
const parent = Node.has(editor, path) ? Node.parent(editor, path) : fallbackParent
// or, if only the path is needed:
const parentPath = Path.parent(path)

Defensive patterns

Strategy: validation

Validate before calling

if (!Node.has(root, path)) { /* path invalid; re-derive */ }

Type guard

const parentPath = (p: Path): Path | null => p.length > 0 ? Path.parent(p) : null

Prevention

Prefer Path.parent when you only need the path, not the node.
Check Node.has before Node.parent.
Re-derive paths after document mutations.

When it happens

Trigger: Calling Node.parent(editor, [0, 0, 0]) where node [0,0] is a text node (i.e., a child-of-text path); using a path that was never valid in this document after the tree changed shape; passing a path one level deeper than any real node.

Common situations: Stale paths captured before normalization or collaborative edits restructured the document; path arithmetic that appends an extra index; iterating with a custom traversal that produces impossible paths.
