Setting up wks/ error parsing submission email

[fsantiago@deviltracks.net]

Hi,

I’m setting up (or trying to) wks on my email server, which is Ubuntu 18.04 using postfix / dovecot with procmail. I think I’m close but keep getting an error in my procmail output when I test it from another machine using the command line client test noted in the GnuPG docs. The 2nd machine is also Ubuntu but using its stock gpg (older rev as you can see in the log output below). The email server has been setup with the current gpg as noted in the instructions:
 
gpg-wks-server: gpg: public key is 79080E479BBBDB96
gpg-wks-server: gpg: WARNING: server 'gpg-agent' is older than us (2.2.4 < 2.2.9)
gpg-wks-server: gpg: Note: Outdated servers may lack important security fixes.

gpg-wks-server: draft version 2 requested
gpg-wks-server: parsing decrypted message
gpg-wks-server: no suitable data found in the message

i followed the GnuPG wikis / doc webpages for this setup. I can’t get past this last error. Any ideas? Thanks.
