I have a form that takes an attachment as one of the questions. It is always just 1 excel file (xlsx). Then I need to take the attachment and insert it into an Approval. No changes need to be made to the file in the process. I've tried several things, but I always end up with a message from Excel saying that the file is corrupted. If I specify the MimeType (which I've verified several times is the correct MimeType), then the Approval message doesn't include the attachment.
