My guess would be that you have something in the session and you are not
guarding against the case where it is missing and then trying to return it
as part of the context.
You should add a null check and do the right thing for your app.

when you open a page, and leave it there for quite a long time, then come
back, click somewhere, it shows error like this:
An unexpected application exception has occurred.
Context values (which are added to the request URL) may not be null or
blank.
