object is not an instance of declaring class java minecraft

I am making a minecraft PVP client and when using the reflect method I keep getting this error:

java.lang.IllegalArgumentException: object is not an instance of declaring class

Event.java

package Val.events;

import java.util.ArrayList;

public class Event {
    
    public Event call() {
        
        final ArrayList<EventData> dataList = EventManager.get(this.getClass());
        
        if(dataList != null) {
            for(EventData data : dataList) {
                try {
                    data.target.invoke(dataList, this);
                } catch(Exception e) {
                    e.printStackTrace();
                }
            }
        }
        return null;
        
    }

}

I've looked at the reflect method class but it seems fine to me.

Thank you for you're help.
