Missing events with AWS Lambda

[colet12]

Expected Behavior

As an event is being sent, without any batching, I would expect to see it in Amplitude. However, I do not see every event, and some go missing.

Steps to Reproduce

Configuration:

Initialize Amplitude client

api_key = get_amplitude_api_key()
amp = Amplitude(api_key)
amp.use_batch = False

def send_to_tracking_api(user_id, data):
user_id = user_id
event_name = data["action"]
print(f"Sending tracking event {event_name} for user {user_id}")

try:
    event = BaseEvent(
        user_id=user_id,
        event_type=event_name,
        event_properties={
            "started_at": data['started_at'],
            "task_content": data['task_content'],
            "timestamp": data["timestamp"]
        }
    )
    amp.track(event)
except Exception as e:
    print(f"Error sending tracking event: {e}")

Environment

• SDK Version: 1.1.4
• Python Version: 3.12

(Advice warning- I'm an Amplitude noob)

You probably need to call flush() before the lambda handler returns.
