The error means you are trying to access a non-instantiated object, but it doesn't say where (usually the backtrace will give you some lines to look at, which could be that you don't have all the lines posted here). You'll need to walk that through a debugger. Its possible as well that there is a throws that is tossing null.
It is potential that the underlying cause is external such as your database. NullPointerException is tossed off of any null object, which would include a failed attempt at connecting to a database. If it is tossed from here, it would indicate a poor implementation of error checking.PHP Code:
header('HTTP/1.1 420 Enhance Your Calm');
