I have a geoprocessing task that currently runs OK in a ArcGIS Online Web App Builder app. One of the input paramters (type=GPDataFIle) allows the user to upload a file, which then gets processed by the task. Now we are moving to ArcGIS Online Experience Builder so I create a Analysis widget and specify the task as a Custom Web Tool. We when I go to run the tool, that input parameter no longer appears to support file upload. Instead the I can only select an item form My Content, My favorites, ... Living Atlas, and ArcGIS Online. Is this a mistake? How or when can I do the file upload?
Update: Even worse, it looks like the file type is limited to just PDFs, CSVs, and Word Documents. Other file types such as zipped shape files are not allowed
