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-TypeLoadException-RequestID/td-p/626915 . 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
