Firebase云功能-权限被拒绝

Question

我正以管理员身份面对Firebase函数并遇到问题。

根据此https://firebase.google.com/docs/functions/beta-v1-diff#realtimedatabase adminRef替换为ref 。

然后我使用change.after.ref，但仍然出现Permission denied错误。

我做错了什么？我只想在/stripe_customers/QymIMpC0ZccSG5mGdFFMdgBksFq1/customer_id

上设置一个值

我不确定是否已正确设置process.env.FIREBASE_CONFIG

exports.createStripeCustomerManual =  functions.database.ref('/Users/{userID}').onUpdate((change, context) => {

    // const beforeData = change.before.val(); // data before the update
    const afterData = change.after.val(); // data after the update
    const userID = context.params.userID;
    const email = afterData.email;
    console.log('createStripeCustomer', afterData, userID, email);

    const appOptions = JSON.parse(process.env.FIREBASE_CONFIG);
    appOptions.databaseAuthVariableOverride = context.auth;
    const appCSCM = admin.initializeApp(appOptions, 'appCSCM');

    const deleteApp = () => appCSCM.delete().catch(() => null);

    return appCSCM.database().ref("/stripe_customers/"+userID+"/customer_id")
            .set("Firebase please DO IT AS AN ADMIN!!!!").then(res => {
                // Deleting the app is necessary for preventing concurrency leaks
                console.log('stripe user created!');
                return deleteApp().then(() => res);
            })
            .catch(err => {
                console.log('ERROR cscm: ', err);
                return deleteApp().then(() => Promise.reject(err));
            });

});

package.json

错误：
