We are having an issue with workflow for one of our clients.
The WF is simple: In Alteryx Gallery accept a file as an Input from the User and then send it to FTP Location.
The File format is : xlsx , txt file and an file with no extension (but is a txt file).
The WF works fine when RUN on Alteryx Designer on a local computer but fails on Gallery interface. On input of a file it shows "File Format not supported"
The WF is attached with the post.
Screenshot's also attached


Can anybody help as to what is the reason are we doing anything in-correct?
