I recently moved a section of an on Premise Sharepoint 2013 to Sharepoint Online.
The main function of this section is for expense submissions, for this there is a library with a default form for employee expenses created via Infopath.
The form works and calculates fine, however upon submitting the form the following error is given. I have tried editing permissions for the submitting user to include edit and full control, but neither give any better results.
Any idea what the issue might be?
