Thanks in advance

man so many things could cause that

most often when i've got that error it's due to not having the table setup correctly.

we really need more information, more stack trace, more code.

you'd probably be better off turning the logging up to DEBUG and step through the code with a debugger. or if you don't have that capability, throw some print statments in there to check if stuff isn't null etc
