A State Processing Engine
Here’s how I built a flow-based state processing engine using platform events. It allows for high volume asynchronous processing of records that will come from an integration.

What I've Learned about Platform Events
Platform Events are a great tool to add to the admin's toolkit, but they take a moment to wrap your head around. And for those of us that are declarative-only, their strong scent of "developery-ness" adds to the wariness. But once you break them down, they can be pretty handy!

onError(error => {
console.error('EMP API error: ', JSON.stringify(error));
});
}
subscribeToPlatformEvent() {
try {
const messageCallback = response => {
console.log('Message received:', response);
try {
if (!this.isComponentConnected) {
// Component is disconnected, no need to process the event
return;
}
const agentNumber = response.data.payload.Agent_Number__c
// Display a toast message for every incoming call
const toastEvent = new ShowToastEvent({
title: 'Incoming Call',
message: `Incoming call from ${agentNumber}`,
variant: 'info',
});
console.log('Successfully subscribed to : ', toastEvent);
if (this.isComponentConnected) {
this.dispatchEvent(toastEvent);
}
console.log('Successfully subscribed to : ', this.dispatchEvent);
} catch (error) {
console.error('Error handling message: ', JSON.stringify(error));
}
};
// Subscribe to the Platform Event
subscribe(this.channelName, -1, messageCallback).then(response => {
console.log('Successfully subscribed to : ', JSON.stringify(response));
});
} catch (error) {
console.error('Error subscribing to platform event: ', JSON.stringify(error));
}
}
// Unsubscribe when the component is destroyed
disconnectedCallback() {

The [NoErrorObjectAvailable] Script error you're seeing, suggests that there's an issue with a script running in your Salesforce org. This error commonly arises in situations where there is an uncaught JavaScript exception or an issue in the LWC component that is affecting the user interface.
These steps may help resolve your issue,
1. Check Browser Console for Details
The error message itself, [NoErrorObjectAvailable], is a generic one, so it doesn’t provide much specific information. However, opening your browser's developer console might show more detailed error logs.
2. Put the code in try-catch block where the potential error lies. It is always recommended to use try-catch in your code to catch this type of error.

Hi All,
We wish to create an automation which tests if a certain platform event has been fired successfully or not.
However, unable to figure out if there is any object/soql that can help us assert that.
Just to add more, there is no subscriber of this event in salesforce itself.
Any approaches?
Thanks
You can refer to the following link of "Monitor Platform Event Publishing and Delivery Usage ".
Thanks

We have a record trigger flow creating a Platform Event. If the a textfield is null (blank), the payload from the Platform Event is showing None. How can we fix this to show ''?
What we really want is an empty string instead of it saying None. We can't figure out where None is coming from. We are using a text field.
Hi All, I have been reviewing the platform event usage of an org and I noticed that limit on 'Event Publishing' was more than 500,000 a day while the limit of the org is 250,000 as mentioned below.
"Event Publishing: maximum number of event notifications published per hour : 250,000"
Do you know if this limit is a soft limit as we have not noticed any process failing due to the breach of this limit.
These are a mix of events including the change type as well as custom platform events. These are regarding the 'publish' events. Most of the instances are of CHANGE_TYPE for record changes of object like account.
I've been testing with ChangeEvents and Change Data Capture in my sandbox and I've been running into some weird behaviour when trying to playback old events.
I updated a 1000 accounts and made sure not much other changes where made to accounts afterwards, the first 2 days I could retrieve the accounts via replayId no issue. After receiving the last 100 updated accounts and sending another call to fetch changes I would get back an empty message and nothing was added up to my delivered event limits.
However on the 3rd day before hitting the 72 hour limit, I tried to fetch the accounts using ReplyId as I did before. However after the last 100 updated accounts where fetched sending another message did not result in an empty message as a response instead I got another message with changes and a absurd amount of delivered events was added to my limit something along the lines of 24.000 even though over those 3 days no more then 550 events where delivered according to the platformusagemetrics records. What could have caused this?

Is it possible to use Platform Event creation in certain topic and Subscription of Lightning Component to this topic - to Pop-Up the exact object records at the exact User's screen, the same time while the request comes to the REST-service from the external system? This REST-service will create this Platform Event.
The main questions are:
1) Would the Platform Event be created the same time the request for the creation comes (or any delays are possible - what would be the delay)?
2) Would the Platform Event be read by the subscriber the same time it is created (or any delays are possible - what would be the delay)?
The amount of the Platform Events in this topic is going to be approximately before 40 000 per day.
Business need: To pop-up records at the user screen "the same time or with low delay" when the event comes from the external system.

Hi,
Platform events and push topics are for real time notifications. When the platform event is published, the subscriber receives it instantly. You can easily test it.
1. Create a Platform event.
2. Create a LWC to subscribe to it.
3. Use Workbench or Developer Console to publish to the Platform events.
4. Check the LWC whether it is getting it without any delay.
Sample LWC - https://www.infallibletechie.com/2021/10/how-to-subscribe-to-platform-even-using.html
