After having another look and playing with the code a bit, it looks like my initial suspicion was wrong. The offending part of the code is not the AwsClientBehavior type, but rather Behavior::commandCalls. If you tweak the tsconfig to only build awsClientStub.ts, it will throw with the mentioned error by default, but succeed if Behavior::commandCalls is commented out.

Maybe someone can make use of this starter for an actual fix

I’m on vacation for the next 2 weeks, so I won’t be able to work on this soon. But I can review a PR if someone creates a fix.
