Looks like that is getting rid of my error, I'll try it and see if it'll run.
Having to use escape characters inside a string for anything more than a quote always feels so clunky to me. I figured it would get passed into the function fine (since that string passes into the out of the box functions with no issues), but it would need some kind of brackets around it inside the function, so that's where I was trying to change it.
The scripting language in Data Services always feels just consistently inconsistent enough that it always throws me off.
