Device generation generic error on config groups in sd-wan

[stephon.a.it]

I have a sd-wan lab in eve-ng and I'm working with config-groups for the spokes. When I get to the point to preview the CLI, an error displays which I will attach below. I've never seen this error before and I remember being able to push this config group before. Has anybody came across this error?  Thanks

Versions:

Controller suite - 20.12.4

C8kvs - 17.12.04

It seems that vMange isn't able to decrypt some referenced secret in the configuration. Can you share some information re. the templates you have configured? My first instinct is that this sounds like a software problem, I would try upgrading to 20.12.4.1 as I see 20.12.4 is deferred.

Thanks for your reply. You mentioned decrypt so I immediately thought about aaa and tried to investigate that sub-feature profile. I was unable to open the profile with a generic error. highly suspicious. So I'll take your recommendation and upgrade the controllers and see if there's a difference.
