SIGTERM in our container before it gets the SIGKILL. We added logging on a SIGTERM that never seems to trigger. We tried to manually do it via this.stop(), and it's not getting it via the default activityExpired handler either...SIGTERM by SIGKILL it all works. Code is below:

onContainerRequest in container enabled durable objects, I keep getting the error: This member cannot have an 'override' modifier because it is not declared in the base class 'DurableObject<Env, {}>'.
