调用企业微信api外部联系人中的删除标签接口https://qyapi.weixin.qq.com/cgi-bin/externalcontact/del_corp_tag?access_token=ACCESS_TOKEN，调用后提示报错

{
    "errcode": 41017,
    "errmsg": "missing tagid, hint: [1599377437_100_bda188e1ad69afb33aff34b94323fced], from ip: 116.235.164.227, more info at https://open.work.weixin.qq.com/devtool/query?e=41017"
}

我这边请求参数如下

{
    "tag_id": [
        "et8jRBDgAAdc0jqXmEzq_JUp_oS1YsBg"
    ]
}

看上去和文档是一样的，请问应该怎么解决？
