Same problem with that log. What it looks like is maybe you copied-and-pasted the yaml patch from my post, but didn't scroll down far enough to copy the whole patch. This could be a bit of an issue with the yaml format because there is no end-of-patch marker, so if a bit is left off the end there is no error to tell you that the patch is incomplete.

Spoiler:
