Thanks for the reviews. I'm going to hold off on merging this for a bit. The environment that was showing these errors is now, inexplicably, not showing these errors. Even without the fix.

I want to confirm this actually fixes something before merging.

EDIT: I have seen now seen it once on the old image. I'm going to go ahead and merge this.
