Errors with reading multiple files from a folder - Alteryx Gallery

[JinoGeorge]

Requirement is to read multiple .dbf files from a folder and create trial balance report, the write to an excel sheet. This needs to be published in the Alteryx Gallery and users should be able to point the folder which contains the .dbf files and gallery should be able to perform the rest and provide the output. I have done this in my local with folder browse and directory tools and getting errors while saving it in my local studio. I have read, folder browse and directory tools are not supported in gallery and tried some other options. All ended up in vain. 

Can someone help me here please with a solution which will work in gallery? I have tried as per the solution https://community.alteryx.com/t5/Alteryx-Designer-Discussions/Problem-loading-app-Unknown-error-Type... . But unfortunately it didn't work out for me. 
I am attaching the app and two input files here. (Original app was bigger, so I deleted few steps to focus on the multiple files reading part)

Received the below error while saving the app in my private gallery

And the below message while trying to run in private gallery

Hey @JinoGeorge ,

Here I`m talking exactly about this limitation. https://community.alteryx.com/t5/Alteryx-Server-Discussions/How-to-insert-path-to-Alteryx-gallery/td...

In summary, you have to use a shared folder which both you and the server have access to. From the print screen you shared, I can see the Gallery is trying to reach a file in your desktop which is not possible.

Best regards,
