Getting something went wrong error while calling cometd library in chrome

[itssonamsinha]

CometD version(s) : 8

Java version & vendor (use: java -version) : openjdk 11.0.15

Description
"Getting something went wrong error" while hitting cometd library in chrome whereas on clearing the cookies it is working fine.
We are observing there are no issue with firefox.

How to reproduce?
We have created an apex component which configures , listens and suscribes to the event. We have written another visual force page to call this component and render the result on our page.

<apex:component>
    <script>
        $(document).ready(function(){
            $.cometd.configure({
                url: window.location.protocol + '//' + window.location.hostname + '/cometd/49.0',
                requestHeaders: { Authorization: 'OAuth {!$Api.Session_ID}' },
                appendMessageTypeToURL: false
            });

            // Define a variable to track handshake state
            var isHandshaken = false;

            // Add a handshake listener
            // $.cometd.on('handshake', function(message) {
            //     isHandshaken = true;
            // });

            // to avoid illegal state, handshake done only once on page load
            if (!isHandshaken) {
                console.log('before handshake');
            
                // disable websockets
                $.cometd.websocketEnabled = false; 
                    
                $.cometd.handshake();
                
                console.log('before addListener');  
                
                $.cometd.addListener('/meta/handshake', function(message) {
                    if (message.successful) {
                        console.log('Handshake Successful: ' + JSON.stringify(message));                 
                        subscription = $.cometd.subscribe('/event/xxx', 
                                            function(response) {
                                               
                                                if (subscriptionResponse.Status === "Success" ) {
                                                    $.cometd.unsubscribe(subscription);
                                                } else if (subscriptionResponse.Status === "Failure") {
                                                    $.cometd.unsubscribe(subscription);
                                                }
                                            },
                                            function(subscribeResponse) {
                                                console.log('Response on subscribing to event->xxx : ' + JSON.stringify(subscribeResponse));
                                                eventSubscriptionSuccessful = subscribeResponse?.successful;
                                            }
                            );
                    } 
                });
            }
        })
    </script>
</apex:component>

You appear to be using SalesForce's products.

While they are based on CometD, SalesForce made modifications that we do not know, so we cannot really help here.

You should contact SalesForce support for your problem.

we wrote the implementation as above and imported cometd libraries in another visualforce component to call this component. We don't have any logs as page starts throwing the above error. We are the ones who are doing the implementation

Can you please help us here?

Your usage of the CometD APIs is correct.

However, CometD does not define any application message, so the format of messages in your message listener for channel /event/xxx is defined by SalesForce.

As for the crash of the tab/window in Chrome, that is a Chrome bug and there is nothing we can do.
No JavaScript code should be able to crash a Chrome tab.

Sorry, but for what pertains CometD, you are doing things right.

There is nothing we can do regarding the server-side (SalesForce) or Chrome crashes.
