I’m having an issue while trying to upload some submissions manually. Those were sent by a data collector, but I got the following error:
I tried to complete a submission myself to rule out any errors on the export process and still got the same error. I´m following the instructions on the support site as suggested in this entry and this other one.
It is a process that I have completed successfully before, so I really don’t know what the issue is.
Thanks in advance for your help.
