Message duplication issue

General
1

message observer method calling multiple times after sending message which is causing message duplication issue but after calling message list API again we are getting proper messages but during sending message we are facing this issue

Hello, we have been facing the issue of duplicate messages from past 2-3 months and have reported this issue earlier as well. Whenever we type the message it gets send duplicate times. Can you please check and give us a proper solution to it. We are soon going to launch the product and cannot take the product live with such issue as it would create a very bad impression on the user.

Can you please give us a solution for the duplicate message asap, as we have been facing this issue for a long time? Our client is planning to go live in the next 10 days and we would need a proper solution before going live. Please take this as a priority now. Also if we are not able to fix the issue then please do keep us posted about it as well, so that we can look for other solutions.

Hello @harshit sorry for the late response, from what we have conducted the investigation, this issue doesn’t occur in the newer version(above .35) anymore. However, we are currently working on a known issue that might be related to the msg creation. We will keep you informed on the result.

17

ok we are waiting for your reply as this bug impact user experience

Can you provide an estimated date on when we can expect the issue resolved? As mentioned our client is planning to go live by 2nd week of feb, so we would need it solved before that in .35 version.

Please try this code below, this should solve the message duplication issue

let tempMid: string = "";
useEffect(() => {
    observeMessages(channelId, {
      onEvent: (action, message) => {
        if (action == "onCreate") {
          if (message.data?.uniqueId === message.data?.messageId) {
            return;
          }

          if (tempMid != message.data?.messageId) {
            tempMid = message.data?.messageId;

            if (messages.find(item => item.messageId == tempMid)) {
              return;
            }

            setMessages((prevMessage) => [message.data, ...prevMessage]);
          }
          
          if(friendData) {
			dispatch(notifyOnNewMessageSend(message));
		  }
        }
      },
    });
  }, [channelId]);
