Typescript Firebase云功能的本地测试失败

我想在我的本地计算机上测试我的简单云功能，这样我就不必每次更改代码时都部署它

我已经重新登录到firebase，现在使用firebase shell调用函数

这是我的云函数代码，但到目前为止我还没有执行它

export const getPossibleFriend = functions.region('europe-west1').https.onCall((data, context) => {
    console.log(data);
    const json = JSON.parse(data);
    console.log(data);
    console.log(json);
    console.log("OAHOIODHSDHHID")
    let test:string;
    const parentRef = admin.database().ref("users");

    return parentRef.once('value').then(snap => {
        snap.forEach(function(child) {
            if(child.child("nickname").val() === json["nickname"]){
                console.log(child.val());
                test = child.val();

            }
        });
    }).catch(reason => {
        console.log(reason);
    }).then(() => {console.log(test);return test}).catch(reason => {
        console.log(reason);
    });

});

每次使用firebase函数时：shell和call： getPossibleFriend（{“数据”：{“昵称”：“某些字符串”}，“上下文”：{“asdf”：“asdf”}}）

我得到：
