    In which file is the error? Can you post the relevant code part from this file? – lxg Sep 08 '14 at 08:07

Property k in the google maps api is one of the values it uses internally. Your code is breaking before it gets there though, you've forgotten to initialize or get some object before using it.

In JavaScript this is complicated by the fact that you can get this kind of error in cases where you have code like

foo.bar.props['example'].things

and you'll get an error about trying to access property 'things' if foo is undefined or null.
