If alteryx can't create a .yxzp file from your workflow - it won't be able to upload to sever. It seems to have an issue with one files name. I'd recommend trial and error to figure out which one can't be included in a .yxzp - and then changing the name of that file. If you post this on the Designer thread vs the Cloud Designer/Trifacta thread - you'll get more of a response.
