Solution here:
So the node “Create Event” is basically the way to bind a function (class method) to Event Dispatcher (basically, the same as “Custom Event”, but instead of an event a function is used). Signatures for Event Dispatcher and function should match, only then you can see you function in the list of possible functions.
The already created Custom Event for this event was the problem. In details panel you need to make sure the inputs match those of the Event Dispatcher
