Issue with Trading API - corporate announcements

Alpaca Integration Applications
1

I’m trying to find recent splits, what am I doing wrong?

from alpaca.trading.client import TradingClient
from alpaca.trading.requests import GetCorporateAnnouncementsRequest
from alpaca.trading.enums import CorporateActionDateType, CorporateActionType

trading_client = TradingClient(key, sec, paper=False)
    
trading_client.get_corporate_announcements(
    GetCorporateAnnouncementsRequest(
        since=datetime(2024, 5, 13).date(),
        until=datetime(2024, 5, 14).date(),
        ca_types=[CorporateActionType.SPLIT]
    )
)

Returns the following:

---------------------------------------------------------------------------

     14         ca_types=[CorporateActionType.SPLIT]
     15     )
     16 )
