Data App - User Uploads Files to Use as Data Source

Hello!

I am creating a data app so all my nodes are inside a component. My data source is 6 .txt files, but I would like to make it possible for the user to select which files to use. I currently have the Multiple File Upload Widget (labs). However, it only works when I edit the node itself (apply changes temporarily & close) to change the files. When I open the entire component, change the files and press refresh nothing happens. I have also deployed the workflow as a data app, and it’s the same. The user is able to upload files, but it doesn’t affect the rest of the workflow.

I tried to use the File Upload Widget, it could work to upload the 6 files separately, but the same issue persists.

You’ll see in my workflow, I check that there are 6 files, in order to proceed. Otherwise, it gives an error message “Not enough files uploaded.” And in the second picture, I have uploaded 6 files, pressed the refresh button but the nodes don’t run again.

Does anyone have any ideas about why it’s like this or what I could do differently?

Thank you!
