Based on docs, but this is a bummer for testing purposes.
SAM 6.2 beta can be installed standalone for beta testing, or in conjunction with the NPM v12 beta. SAM 6.2 is still beta, and as such should not be installed on top of your production Orion installation. I believe this is the reason why you are receiving the error that you are.
ah, yes..this is in lab env, but I see your point
