I think I got it. It was a spelling mistake at:
missing letter inside the "" that the compiler could never had found, and
the fields were not being set correctly
Thank you very much for your time, your reply helped me to look at the
correct place.

this is a line of code in your code.  Likely timeoutstart or timeoutstop 
is null.   So either the wrapper we returned is null or you didn't get 
the wrapper.  Make sure timeoutstart and timeoutstop are not null.
