THEN Switch to a docstore that properly handles Document serialization, such as InMemoryStore, or override LocalFileStore.mset to serialize Documents to bytes before writing (e.g., using json.dumps(document.dict())).

class FixedLocalFileStore(LocalFileStore):
    def mset(self, key_value_pairs):
        for key, value in key_value_pairs:
            if hasattr(value, 'dict'):
                value = json.dumps(value.dict()).encode()
            super().mset([(key, value)])
