Get the list of children issue

When I tried to apply rest api to get children like following.

https://test.com/rest/wikis/xwiki/spaces/XXX/spaces/test/pages/WebHome/children

I could only get the page tag result like following.

<pages/>

Where is child list ? and how can I get them ?

When I tried
https://test.com/rest/wikis/xwiki/spaces/XXX/spaces/test/pages/WebHome/

I can get following

<page>
<id> </id>
<fullName></fullName>
<wiki></wiki>
<space></space>
<name></name>
<title></title>
<parent/>
<parentId/>
<version>12.1</version>
<author>XWiki.test</author>
<xwikiRelativeUrl>https://test.com/bin/view/XXX/test/</xwikiRelativeUrl>
<xwikiAbsoluteUrl>https://test.com/bin/view/XXX/test/</xwikiAbsoluteUrl>
