We can see _rw_kafka_partition is the cause.

Caused by:
    statement failed: db error: ERROR: Panicked when handling the request: a stream key is expected but not exist, plan:
    StreamHashJoin [append_only] { type: Inner, predicate: seller = _rw_kafka_partition }
    ├─StreamExchange { dist: HashShard(seller) }
    │ └─StreamFilter { predicate: (category = 10:Int32) }
    │   └─StreamRowIdGen { row_id_index: 11 }
    │     └─StreamSourceScan { columns: [id, item_name, description, initial_bid, reserve, date_time, expires, seller, category, extra, _rw_kafka_timestamp, _row_id, _rw_kafka_partition, _rw_kafka_offset] }
