When I try to publish my application to the Alteryx Gallery I am receiving a "File Not Found" error for my input files. Error is pictured below.

I followed the instructions found here: https://community.alteryx.com/t5/Alteryx-Knowledge-Base/Avoid-getting-quot-external-1-quot-when-Publishing-an/ta-p/39274 to insure that the input and output file will keep the same path and not be kept in external folders. By using the "Manage workflow assets" options I have kept my input & output file paths absolute (C:\Users\etc.) rather than relative (.\etc) by making sure the input and output files I want to keep absolute are unchecked. I have verified that my workflow dependencies are all full UNC paths and that the server has access to the mapped drive where the input files are store. However I am still getting an error.
