Hi

We have a requirement to get the EDI file from FTP and send the EDI file in email as attachment. We created the flow with Pre built solution - Send an email w/ attachments is not working as expected. The Pre built solution have map and post map hook. We received the email with attachment file without actual data. It is having some random characters. How send EDI file as attachment in email?
