openclaw - 💡(How to fix) Fix [Bug]: WhatsApp Web listener running but inaccessible to message handler [7 comments, 5 participants]

• Error: Error: No active WhatsApp Web listener (account: default) ❌

Fix Plan

To resolve the issue of the message handler being unable to communicate with the running WhatsApp listener, we will focus on the potential handler/listener routing issue, IPC/socket communication breakdown, or process isolation problem. Given the information, a key step is to ensure proper communication between the message handler and the WhatsApp listener.

Step-by-Step Solution:

1. Verify Listener Configuration: Ensure the WhatsApp listener is correctly configured to communicate with the message handler. This involves checking the listener's settings for any misconfigurations that might prevent it from being recognized as active by the message handler.
2. Check IPC/Socket Configuration: If the listener and handler use IPC (Inter-Process Communication) or sockets for communication, verify that these are correctly set up and not blocked by any security policies or firewall rules.
3. Process Isolation: Ensure that the WhatsApp listener and message handler are not isolated in a way that prevents them from communicating. This could involve checking Docker container configurations or system-level isolations.
4. Update OpenClaw Configuration: If using a version-specific configuration, ensure it's updated to match the 2026.3.13 version of OpenClaw. Sometimes, configuration formats or requirements change between versions.

Example Code Snippet for Verification:

To verify the WhatsApp listener's status and its ability to communicate with the message handler, you can use a simple script. For example, in Python, using the subprocess module to interact with the OpenClaw CLI:

import subprocess

def check_listener_status():
    # Check the status of the WhatsApp listener
    status_command = "openclaw channels status --probe"
    try:
        output = subprocess.check_output(status_command, shell=True).decode('utf-8')
        if "running, connected" in output:
            print("WhatsApp listener is running and connected.")
            return True
        else:
            print("WhatsApp listener is not running or connected.")
            return False
    except subprocess.CalledProcessError as e:
        print(f"Failed to check listener status: {e}")
        return False

def send_test_message():
    # Attempt to send a test message
    send_command = "message action=send channel=whatsapp target=+447501726862 message='test'"
    try:
        subprocess.check_output(send_command, shell=True)
        print("Test message sent successfully.")
    except subprocess.CalledProcessError as e:
        print(f"Failed to send test message: {e}")

if __name__ == "__main__":
    if check_listener_status():
        send_test_message()
    else:
        print("Cannot send message. Listener is not active.")

Verification

• After applying the fixes, restart the Docker container and the WhatsApp listener.
• Run openclaw channels status --probe to verify the listener's status.
• Use the provided Python script or a similar method to test sending a message through the WhatsApp
