Inconsistent Event Reporting - Unknown error

[wrong1man]

Hello,

I've been using the Facebook Business SDK for Python to report events, but I'm experiencing inconsistent results. Some events are reported successfully, while others fail without a clear explanation from the traceback.

here's the traceback:

Traceback (most recent call last):

and here's the implementation:

def meta_api_send_event(emails, client_ip,user_id,ph,date_of_birth,first_name, client_user_agent, fbc, fbp,timestamp,
               event_name, event_source_url, action_source,quantity=None,product_id=None,currency=None, value=None, description=None):
    '''

    :param value: float
    :param event_name: str

    see example usage bellow
    '''
    user_data = UserData(

        fbp=fbp,
    )
    if ph != None and ph[0] != "None" and ph[0] != None:
        user_data.phones=ph
    if product_id and quantity and value:
        content = [Content(
            product_id=product_id,
            quantity=quantity,
            item_price=value,
            description=description,
        )]
    else:
        content=None

    custom_data = CustomData(
        contents=content,
        currency=currency,
        value=value,
    )

    event = Event(
        event_name=event_name,
        event_time=int(timestamp),
        user_data=user_data,
        custom_data=custom_data,
        event_source_url=event_source_url,
        action_source=ActionSource[action_source],
    )

    events = [event]

    event_request = EventRequest(
        events=events,
        pixel_id=pixel_id,
    )
    event_response = event_request.execute()
    return event_response

The issue seems to occur inconsistently. Some events pass through without any issues, while others fail. I haven't been able to identify a pattern or specific cause for these failures.

The lack of detailed information in the traceback makes it difficult to diagnose and address the issue. I'm hoping for some guidance or insight into what could be causing these inconsistent results.

Thank you for your assistance!
