dd.saveFileToDingTalk报错 No permission info for...

调用dd.saveFileToDingTalk报错提示 No permission info for action: biz.cspace.saveFile。但文档说saveFileToDingTalk调用无需鉴权啊，https://open.dingtalk.com/document/isvapp/jsapi-save-file-to-ding-talk。我的代码是这样写的：
dd.saveFileToDingTalk({
name: "大合照.png",
url: "https://gw.alicdn.com/imgextra/i3/O1CN01Eg6xCm1nnsXZCnkP4_!!6000000005135-2-tps-200-200.png",
success: (res) => {
const { data } = res;
console.log("保存成功", res);
Taro.showToast({ title: "保存成功", icon: "success" });
},
fail: (err) => {
// 打印详细错误信息
console.error("保存失败，错误详情：", JSON.stringify(err, null, 2));
alert(JSON.stringify(err));
// 显示错误信息到用户界面
Taro.showToast({
title: 保存失败: ${err.errorMessage || "未知错误"},
icon: "none",
duration: 3000,
});
},
complete: () => {
console.log("保存操作完成");
},
});
