I tried to run stack_master status in an environment with a few stacks and unfortunately I got no results due to a parameter missing:
error: Unable to resolve parameter "ShopfrontExtAlbSg" value causing error: Stack with id shopfront-ext-alb-sg does not exist. Use --trace to view backtrace
This feels like the wrong behaviour for status. If the stack cannot be parsed it should be listed as "unknown" and not stop the rest of the stacks from being listed.
