new Rest API ID is being generated on each deploy

whenever I run chalice deploy it creates a new api id. why is this happening and how do i fix this?

Start by reproducing the behavior with `chalice deploy` and inspect how deployment state and the REST API ID are handled between deployments. Determine the expected reuse behavior, then add or update coverage for repeated deployments and document what “done” means: subsequent deploys retain the intended API identity without creating an unnecessary new API.
