无法将功能部署到 Firebase

Question

当我尝试对用户设置自定义声明时，我无法部署云功能。这是函数

exports.verifyPhone = functions.https.onRequest(async (request, response) => {
    const db = admin.firestore();
    const userId = request.body['userId'];
    const firebaseId = request.body['firebaseId'];

    const now = Date.now();

    const userRef = db.collection('users').doc(userId);
    const updateResult = await userRef.update({
        phoneVerified: true
    });

    const x = await admin.auth().setCustomUserClaims(firebaseId,{folder:userId});
    console.log('folder set');

    if (Number(updateResult.writeTime) > now) {
        return response.json({
            status: 1,
            message: 'Phone verified successfully',
            result: null
        });
    } else {
        return response.json({
            status: 0,
            message: 'An error occurred, please try again later',
            result: null
        });
    }

});

但如果行

const x = await admin.auth().setCustomUserClaims(firebaseId,{folder:userId});

已注释，该功能将部署成功，我已将firebase-admin导入为

import * as admin from 'firebase-admin';

这是日志

我无法弄清楚出了什么问题。谁能告诉代码有什么问题？

如果您查看正常输出（此处未显示）而不是详细日志（您正在显示），则问题很明显。这就是 tslint 告诉你该做什么的地方：

Expression has type `void`. Put it on its own line as a statement.

setCustomUserClaims() 返回一个包含void 的承诺。换句话说，它不会生成任何数据供调用者使用。 TypeScript 告诉您将 void 分配给 x 是没有意义的，您根本不应该分配任何东西：

await admin.auth().setCustomUserClaims(firebaseId,{folder:userId});
console.log('folder set');
