(ERROR) 2018-08-13 11:21:36,780 archive_info.download_if_needed:97  You either aren't authenticated or don't have permission to use the archives for this page set.
You may need to run gsutil config.


root cause:

part of system_health_desktop.json:
"load:media:youtube": {
    "DEFAULT": "system_health_desktop_003.wprgo",
    "linux": "system_health_desktop_003.wprgo",
    "mac": "system_health_desktop_040.wprgo",
    "win": "system_health_desktop_047.wprgo"
},

WprArchiveInfo.DownloadArchivesIfNeeded() tries to download every entry "load:media:youtube", but only the linux entry is necessary.

solution:
story_runner shall call DownloadArchivesIfNeeded() with proper target_platforms to download only the necessary wprgo file.
