Thank you for taking the time. So checking the logs (duh!), it’s telling me that it’s not valid ENML. (My draft is set to export markdown).
So I played around with the specific draft and narrowed it down to two things. Looks like if your first line is blank it will fail. Also if you have this set 
anywhere in the draft it will fail.
Learned something today… with your help!
Thanks again for your time.
