Geek asks and answers

It is not easy to understand the meaning of the stack.

I find it difficult to reprogram the script or read the error below that I received today in my logs. Usually the stack trace will indicate the file and line numbers, etc., but as you can see below, it only speaks of a nullreference exception, not giving me a specific place. I would appreciate it if you could help me read this and find out what is happening.

The top line of the stack trace is from the deepest point (where the error occurred) and the following lines when it creates bubbles to back up the stack.
