openclaw - 💡(How to fix) Fix [Bug]: WhatsApp gateway message duplication on reconnection [1 participants]

TL;DR

Implement deduplication by message_id at the gateway/session injection layer to prevent replayed messages from flooding the session context.

Guidance

• Identify the source of the message replay during gateway reconnection and ensure that messages are checked for duplicates based on their message_id before being injected into the session context.
• Review the WhatsApp gateway's reconnection logic to understand why previously received messages are being replayed and determine if there's a way to prevent this replay or handle it more efficiently.
• Consider implementing a mechanism to track processed message_ids to efficiently deduplicate incoming messages, potentially using a cache or a database to store recently processed message_ids.
• Analyze the logs for patterns or specific conditions that lead to the massive duplication of heartbeat polls and session context saturation to refine the deduplication strategy.

Example

# Pseudocode example of deduplication based on message_id
processed_message_ids = set()

def process_message(message):
    if message['message_id'] not in processed_message_ids:
        # Process the message and add its id to the set
        processed_message_ids.add(message['message_id'])
        # Proceed with message processing
    else:
        # Message is a duplicate, skip processing
        pass

Notes

The effectiveness of the deduplication strategy depends on the implementation details of the WhatsApp gateway and the agent session context. It's crucial to test the solution thoroughly to ensure it correctly handles various scenarios, including different types of messages and gateway reconnection events.

Recommendation

Apply workaround: Implement deduplication by message_id at the gateway/session injection layer. This approach directly addresses the root cause of the issue by preventing duplicate messages from flooding the session context, thus mitigating the problem until a more permanent fix can be integrated.
