I am trying to extract Contact Keys from a data extension so that I can load them back into the system to unsubscribe them. I am gathering these contact keys from multiple SQL Queries to different objects and putting them into the data extension below.
I am running into an issue where my Data Extract Activity is failing. I am running this from an Automation, which is configured as below.
I have tried multiple different data extensions, and all of the three checkboxes but I have had no success.
My Data Extension looks like the following:
The File Transfer setup
And finally the FTP Setup
The error i get is not helpful.
