serialization error while upserting

Hi,
Im getting the following error.

Exception while upserting Error serializing to JSON: UnicodeEncodeError: 'utf-8' codec can't encode character '\udcb0' in position 128: surrogates not allowed

Start with the failing client.upsert call in dynamicbatch_v6.py and trace the serialization path through qdrant_client/qdrant_remote.py, points_api.py, and _pydantic_compat.py. Reproduce the UnicodeEncodeError involving the surrogate character, then establish whether the client should handle or reject this input and verify the resulting behavior.
