Hi, the problem is probably in the urlrewrite filter XML content. You need to provide a URL that matches what XWiki expects, (see https://www.xwiki.org/xwiki/bin/view/Documentation/DevGuide/Architecture/URL%20Architecture/Standard%20URL%20Format/).
The simplest is to follow the example at https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/ShortURLs/#HUrlRewriteFilter
Hope it helps
