    Hi, would you please provide a code snippet causing this error? Right now, the only thing I can tell you is that you're trying to call a method of an object that is not instantiated at that point in time. Here's the documentation of java.lang.NullPointerException: https://docs.oracle.com/javase/8/docs/api/java/lang/NullPointerException.html – Antricks Jun 20 '21 at 10:42
