Hello, I'm new to Xwiki. I'd like to know if they could give me a clue about the following error that is generating me xwiki:

org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Velocity Macro for content [#set ($query = $services.query.xwql('where doc.author = :author order by doc.date desc'))
#set ($recentDocs = $query.addFilter('hidden').addFilter('unique').bindValue('author', $xcontext.user).setLimit(5).execute())
#if ($recentDocs.size() > 0 || $showEmptyPanels)
  #panelheader($services.localization.render('xe.panels.modifications.my'))
  #foreach ($docName in $recentDocs)
    #set ($recentDoc = $xwiki.getDocument($docName).getTranslatedDocument())
    #if ($recentDoc)
      ## We use HTML here because we don't have a tool to escape wiki syntax in document title.
      * {{html}}$escapetool.xml($recentDoc.plainTitle){{/html}}
    #end
  #end
  #panelfooter()
#end]
