I have a flow workspace app that simply takes a shapefile and converts it to a 2D grid, previously (most of 2024) this accepted a zip file of the shape components and worked fine. My user has been using this for months with no problem. Seemingly now it stopped accepting zip files and instead through trial and error i got it working ONLY selecting the .shp component from my PC. This seemed a bit weird as i know it needs more than this but it seemed to work.
I've since downloaded the workspace, made a tiny adjustment to something unrelated to reading the shapefile, republished. This new version now will only work if you select both the .dbf and the .shp, the previous version still works with just the .shp.
I've tried to trouble shoot, recreate the app, anything i can think of but i cant for the life of me explain this inconsistency im finding, has anyone had anything similar?
