Can date type can be updated in graph state?

[jiwonmik]

I have this example data that I want to update to the graph state.

'agent_outcome': {
     'created_at': datetime.date(2024, 6, 17), 
     'month_end_date': datetime.date(2024, 6, 30)
}

But I get this error.

TypeError: Object of type date is not JSON serializable

As I looked through the langgraph/serde/jsonplus.py/JsonPlusSerializer, it handles the datetime type like below,

...
        elif isinstance(obj, datetime):
            return self._encode_constructor_args(
                datetime, method="fromisoformat", args=[obj.isoformat()]
            )
...

Should I convert datetime.date type to datetime.datetime ?
