node.js - GAE version-project-id.appspot.com works but not project-id.appspot.com -

i deployed sample node.js application on gae.

from admin console, under version can see 'version-project-id.appspot.com' url , able access also. version deployed , serving.

however when access 'project-id.appspot.com' url, 404 error.

doesn't project-id.appspot.com url automatically points latest , promoted version-project-id.appspot.com url?

is there other setting make work?

make sure go to:

https://console.cloud.google.com/appengine/versions?project={project-id}&moduleid=default

and set default version want.
