What does it means "Java.lang.class.java.lang.Object.getClass()"

This happens when a line of code is trying to get the class of a null value in Java. It might be the cause of an extension, and you should disable certain blocks to debug.

Thanks, @hammerhai I wasn’t knowing this

If you are creating a dynamic components , and if you have misplaced the get component id block wrongly in place of get id component then this will arise

I think you are right because i used dynamic component extension

I rebuild the function and guess what it fixed
Thanks for your help
