I'm sorry for the misdirect. I'm myself a beginner here! This issue on gitlab is probably the same as the one you are facing. The fix recommended is the installation of falcon 0.3.0.1 or 0.3 https://gitlab.com/mailman/postorius/issues/122#note_4509503
If this doesn't help we'll wait till someone more knowledgeable than me comes along :) Thanks!
