firebase云功能http请求无法正常工作？

Question

当我在Postman上击中API时，我的云功能API无法正常工作，没有错误，只需在Postman上获得404即可。附加了代码和屏幕截图。

index.js

const functions = require("firebase-functions");
const admin = require("firebase-admin");

var serviceAccount = require("./key.json");
admin.initializeApp({
    credential: admin.credential.cert(serviceAccount)
});

const express = require("express");
const cors = require("cors");

// main app
const app = express();
app.use(cors({ origin: true }))

// main database refference
const db = admin.firestore();

// Routes test
app.get("/", (req, res) => {
    return res.status(200).send("test api ")
})

// create
app.post("api/create", async (req, res) => {
    console.log(req)
    try {
        console.log(req)
        await db.collection(useDetails).doc(`/${Date.now()}/`).create({
            id: Date.now(),
            name: req.body.name,
            mobile: req.body.mobile,
            add: req.body.add
        })
        return res.status(200).send({ status: "Sucess", msg: "Data Saved" });
    } catch (error) {
        console.log(error)
        return res.status(200).send({ status: "Failed", msg: "Data not Saved" });
    }
})

exports.app = functions.https.onRequest(app)

firebase仿真器也工作正常

app.post("/api/create", async (req, res) => {

使用 /启动API地址
