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. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/weaviate/weaviate-python-client/eb5546a86204f9b37acb2c226efce00c109768cf/weaviate/exceptions.py (official_docs, unknown, documented_behavior): WeaviateInsertInvalidPropertyError message explains reserved id and vector and recommends DataObject. - https://raw.githubusercontent.com/weaviate/weaviate-python-client/eb5546a86204f9b37acb2c226efce00c109768cf/weaviate/collections/batch/grpc_batch.py (official_docs, unknown, documented_behavior): _validate_props raises for top-level id and for vector at any level.
