Description

Before pressing on "Import Committers from GitHub" I did in previous steps "Update authors with GitHub data" and "Link authors".

My HallOfFame looks like the image.
I want to have the green and red borders, so I'm trying to "Import Committers from GitHub".

Tested on 9.5-RC-1 with the "Admin" user.

The first error I get is:

Failed to execute the [velocity] macro. Cause: [Server returned HTTP response code: 401 for URL: https://api.github.com/repos/xwiki-contrib/macro-spoiler/collaborators]. Click on this message for details.

org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Velocity Macro for content [#if (!$hasAdmin)
  {{error}}You need Administration rights to import Authors!{{/error}}
