Sent API Market Order, Received Accepted Order ID, But Order Does Not Occur

I am using an AWS lambda function to receive alerts and then create an Alpaca Buy/Sell order based on that alert. There are NUMEROUS cases where the AWS lambda function processes the alert, sends the order to Alpaca, and receives a client_order_id showing the order was received by Alapca. Yet the order never actually occurs in my Alpaca account.

Here is an example of an order sent to Alpaca:

{‘symbol’: ‘TSLA’, ‘qty’: 6, ‘side’: ‘buy’, ‘type’: ‘market’, ‘time_in_force’: ‘day’}

Here is an example of a response from Alpaca after submitting the order that shows it was indeed accepted:

{‘id’: ‘8f3f0c14-2023-410e-855e-5cf5bf698b4d’, ‘client_order_id’: ‘a042c699-3b99-41d8-a6fa-5ebf81b557cc’, ‘created_at’: ‘2020-08-24T14:40:01.206037Z’, ‘updated_at’: ‘2020-08-24T14:40:01.206037Z’, ‘submitted_at’: ‘2020-08-24T14:40:01.196926Z’, ‘filled_at’: None, ‘expired_at’: None, ‘canceled_at’: None, ‘failed_at’: None, ‘replaced_at’: None, ‘replaced_by’: None, ‘replaces’: None, ‘asset_id’: ‘8ccae427-5dd0-45b3-b5fe-7ba5e422c766’, ‘symbol’: ‘TSLA’, ‘asset_class’: ‘us_equity’, ‘qty’: ‘6’, ‘filled_qty’: ‘0’, ‘filled_avg_price’: None, ‘order_class’: ‘’, ‘order_type’: ‘market’, ‘type’: ‘market’, ‘side’: ‘buy’, ‘time_in_force’: ‘day’, ‘limit_price’: None, ‘stop_price’: None, ‘status’: ‘accepted’, ‘extended_hours’: False, ‘legs’: None, ‘trail_percent’: None, ‘trail_price’: None, ‘hwm’: None}

However, the order is NOT in my Alpaca account. How can I troubleshoot this further?
