• What is the cause and solution for SAP error message /IWNGW/CM_HUB078 - Ping sent using websocket to recipients for whom do not deliver is false ?

  The SAP error message /IWNGW/CM_HUB078 indicates that a ping was sent using WebSocket to recipients for whom the "do not deliver" flag is set to false. This typically occurs in the context of SAP's integration with WebSocket communication, often used in applications that require real-time data updates.
  Cause:
  
  Recipient Configuration: The error suggests that there are recipients configured in the system that should not receive messages (i.e., they have the "do not deliver" flag set to false), but the system is attempting to send them a ping message.
  WebSocket Connection Issues: There may be issues with the WebSocket connection itself, such as the recipient being disconnected or not properly registered.
  Application Logic: There could be a flaw in the application logic that determines which recipients should receive messages, leading to incorrect handling of the "do not deliver" flag.
  
  Solution:
  
  Check Recipient Settings: Review the configuration of the recipients in the system. Ensure that the "do not deliver" flag is correctly set for each recipient based on your business logic.
  Review WebSocket Implementation: Ensure that the WebSocket implementation is correctly handling the connection states of recipients. This includes checking if recipients are connected and ready to receive messages before sending pings.
  Debugging: If the issue persists, consider enabling debugging or logging for the WebSocket communication to trace the flow of messages and identify where the logic is failing.
  Update Application Logic: If there is a flaw in the application logic, update it to ensure that pings are only sent to recipients who are eligible to receive them.
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance related to the version of SAP you are using, as there may be updates or patches that address this issue.
