Cause (Documented platform behavior): In v4, id is reserved and vector is not allowed at the properties level; custom ids and vectors are passed via DataObject(properties=..., uuid=..., vector=...) or the uuid=/vector= arguments.
Fix status: documented_behavior
Other error fragments:
- You should use the `DataObject` class if you wish to insert an object with a custom `vector` whilst inserting its properties.

Problem details
- Observed symptom
- insert_many/batch raises when a property dict contains a top-level "id" or any "vector" key.
- Context

Proposed fix: [Weaviate Python v4] WeaviateInsertInvalidPropertyError "It is forbidden to insert `id` or `vector` inside properties"
Recommended action: Pop id/vector from the dict and pass DataObject(properties=props, uuid=generate_uuid5(...) or given uuid, vector=vec); rename a genuine "id" property (e.g. doc_id).
Option: Use DataObject for uuid/vector [evidence: official_recommended_action]
Applies when: insert_many
Steps:
1. from weaviate.classes.data import DataObject
2. objs=[DataObject(properties={k:v for k,v in r.items() if k not in ("id","vector")}, uuid=r["id"], vector=r["vector"]) for r in rows]
3. collection.data.insert_many(objs)
Expected: Objects inserted with custom ids/vectors
Evidence basis (self-declared by the contributing chat client): untested.
