I have a power pages portal that is live and open to the public. We have an anonymous page with a multistep form. One of the step has a field to upload a file. The file field is a column in the main table of the multistep form and is marked as mandatory. We have had 1000+ registrations through the form and users have uploaded the file as necessary. When we test too, we cannot go to the next step without uploading the file.
But, around 5 out of the 1000+ users were able to complete the form but without providing the mandatory file. We have no clue what is happening as we have no access to logs. We raised a ticket with Microsoft and it has been ongoing for couple of months. It seems to have been escalated to product group and they are requesting network traces!!. No idea how I would ask everyone coming to my portal to capture network traces and send to me in the hope that the issue gets replicated. For the five cases, we were able to contact the users later and ask them to forward the mandatory files and they all turned out to be just pdfs and when we tested with those, the files were accepted by the portal.
