Can not get Artifact in project with QUERY with DNG OSLC. Acquire Artifact for all projects?

Based on this information,
https://jazz.net/wiki/bin/view/Main/RRCReportableRestAPI#Artifact_types_in_Rational_DOORS
I tried to acquire DNG's project URI, but only one was displayed.
There are about ten project areas that can be accessed, and there are one or more deliverables.
https://server:port/rm/publish/resources/*
Why is it so?
Please tell me how to find out.
When the project ID of a project area that is not displayed is directly specified and executed
It will be "401 Error".
