Error message

本批父节点未提供或不存在

What it means

After merging node fields, mergeBatch validates each node's parent reference: parent must be null (root), an id in the catalog's allowed set, an id present in this batch's patch, or match the node's previous parent. This throw fires when a node points at a parent id that is none of those — i.e., the parent node was not provided in this batch and does not exist in the allowed catalog.

Solutions

1. Constrain the prompt: parents must be null, catalog ids, or nodes within the same batch upsert
2. Pre-validate parent ids against allowed ∪ patch keys before calling mergeBatch and fall back to null or a catalog id
3. Use the repair retry path so the model re-emits the batch with valid parents
4. If cross-batch parents are needed, first create the parent node in an earlier batch, then reference it by its catalog id

Example fix

// before
{n.id:'n_x', parent:'n_ghost', ...}
// after (pre-check)
const allowed=new Set(catalog.map(n=>n.id));
const patchIds=new Set(value.upserts.map(n=>n.id));
for(const n of value.upserts){
  if(n.parent!==null && !allowed.has(n.parent) && !patchIds.has(n.parent)) n.parent=null;
}

const allowed=new Set(catalog.map(n=>n.id));
const inBatch=new Set(value.upserts.map(n=>n.id));
for(const n of value.upserts)
  if(n.parent!==null&&!allowed.has(n.parent)&&!inBatch.has(n.parent)) n.parent=null;

function hasValidParent(n, allowed, inBatch){ return n.parent===null || allowed.has(n.parent) || inBatch.has(n.parent); }

try { mergeBatch(value,...) } catch(e){ if(e.message==='本批父节点未提供或不存在'){ resetInvalidParents(); retryMerge(); } else throw e; }

When it happens

Trigger: Model output sets n.parent to a fabricated id, an id from a different batch, or renames a parent without supplying the parent's upsert; also occurs when the model re-parents an existing node to a new node id not in the current patch.

Common situations: Multi-batch organization where the model builds cross-batch hierarchies referencing nodes created in other batches; hallucinated parent ids after alias remapping.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
