I have a business case where the user wants to send a personalized email to a group of recipients and attach a PDF to the email. I already had a working flow for him that took the list of emails and recipient names in a csv file, parsed those out row-by-row, converted to json, evaluated the json to assign values to attributes, and then send the email (see image), but I'm having trouble with the attachment part since the PDF isn't part of the flowfile. Is there a way to pull the PDF into NiFi and assign the attributes needed from perhaps a map file or something? or replace the flowfile with the PDF and maintain the attributes? Once the attributes are assigned, I don't need the .csv data anymore. Any help would be appreciated! ... View more
