We recently had a workflow developed which copies file attachments from a nintex form and uploads them to document Libraries.
The file gets uploaded, but in SharePoint you cannot open it. We get the following error.
We're sorry, we couldn't open your workbook. It's possibly corrupt or using a file format that's not supported.
If we manually upload the same file to the document Library, it will open in the web app- no problem. Has anyone seen this, or have any suggestions for the fix?
We are using Nintex forms and workflow for Office 365.
