Hi all,
So I just finished this application (which works perfectly on the local server). It's function is to grab all the excel files in a folder, find a specific sheet, and give a summarized output.

However, when I upload the app to alteryx gallery, it gives this error:

It removes the wildcard input that I originally had in the application and only lets me pick one file at a time. It is also not allowing me to upload the file for some reason even to this discussion page. Does anyone have any ideas??
Also
Any help at all is appreciated! Thank you!
