Cannot detect version of OS X Installer. Must be 10.7 or later to deploy it as an upgrade... AKA beating the dead horse?

[easyedc]

Through the last few 10.1x updates I've randomly gotten the error

Cannot detect version of OS X Installer. Must be 10.7 or later to deploy it as an upgrade

but with testing my 10.12 upgrade, I'm seeing this more and more persistently. Has anyone been able to pin-point the cause or come up with a persistent work around? From my /var/log/jamf.log file:

and from my /var/log/install.log:

I went through the system.log as well, with nothing really pertinent in it either.

Thoughts?
