Entity type not found when trying to spawn ch47.entity

Why can't I spawn ch47.entity?
spawn ch47.entity

Code:

(16:42:33) | Entity type not found

 

You are trying it on staging branch right?

 

what is staging branch?

 

u need to have moderator id on staging branch version in order to spawn it in.
Just wait for next months rust update.Should be available then for all of us.

 

thank you very much
