Hi Christian,

Just a follow-up to my last reply. 

What yo are trying to achieve, however, can be achieved by overriding the internal Chat logic:

  function resolveAfter2Seconds() {
    console.log("starting slow promise");
    return new Promise((resolve) => {
      setTimeout(() => {
        resolve("slow");
      }, 2000);
    });
  }
  
  async function someAsyncJob(message) {
  	await resolveAfter2Seconds();
    return message;
  }	
  	
  const originalPostMessage = kendo.ui.Chat.fn.postMessage;
  kendo.ui.Chat.fn.postMessage = async function(message) {
		const m = await someAsyncJob(message);
		originalPostMessage.call(this, m);
  }
  
$("#chat").kendoChat();

Hi Christian,

The Chat post event is an event that triggers when a certain event happens within the component. In the current case it fires when a message is posted to the Chat and can be either through the message box or through an action button click.

https://docs.telerik.com/kendo-ui/api/javascript/ui/chat/events/post

The Kendo UI component events are used to execute custom logic or perform action when an event fires. The post Chat event is not a method that will process events and return a result.

That said, the post event cannot be async. It just captures certain actions and allow you to execute certain logic at that point.

I hope this clarifies the situation.
