When I call obs' hotkeys to stop a recording in python, the video lacks the lastest part(around 3s). If I stop a recording on OBS's GUI, it's ok. What's the problem?

Can I stop a recording in Python without lacking the last part? （I don't use websocket, because it will popup a warning window for access the port）
