As per what the error says, it cannot open that graphics file. The graphics file is probably not where it is supposed to be. The reason you are just now getting the error is because this is the first turn the graphic would have came into play.

To fix it, you probably just need to open the worthy heroes mod, find dogfriend and change the path to "Worthy_Heroes/" instead of the typoed "Worhty_Heroes/".
