Published sbar file produces pink bitmaps in Arnold render

Hi, 

I am a beginner in Designer and currently I have an issue where my Designer sbar isn't properly generating the correct output files. I followed a tutorial on making an asphalt texture. Within Designer itself, my texture renders properly and I can see the correct result. I did my own research on the problem and saw that outdated files (or workflows?) can make materials not generate correctly, but the tutorial is only a year old. Any help would be greatly appreciated!

I am not confident that this will work, but here is a link to a google drive folder with my sbs and sbar: link
