This same code was working perfect the other day, now its not working...

it appears it has something to do with access controls but I cant figure it out.

I found a similar issue on StackOverflow, however, I am not sure where to implement the db.createUser code

here is a similar StackOverflow questions: MongoDB - admin user not authorized

below is my code

[nodemon] app crashed - waiting for file changes before starting...

this is where the server side code is, aswell as all the code::

https://github.com/casas1010/mean-project/blob/main/backend/app.js

i have admin rights and the MongoDB should allowed access from any IP

here is the code making the connection::

const express = require("express");
const bodyParser = require("body-parser");
const mongoose = require("mongoose");

const postsRoutes = require("./routes/posts");

const app = express();

mongoose
  .connect(
    "mongodb srv://USERNAME:[email protected]/?retryWrites=true&w=majority"
  )
  .then(() => {
    console.log("Connected to database!");
  })
  .catch(() => {
    console.log("Connection failed!");
  });

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

app.use((req, res, next) => {
  res.setHeader("Access-Control-Allow-Origin", "*");
  res.setHeader(
    "Access-Control-Allow-Headers",
    "Origin, X-Requested-With, Content-Type, Accept"
  );
  res.setHeader(
    "Access-Control-Allow-Methods",
    "GET, POST, PATCH, PUT, DELETE, OPTIONS"
  );
  next();
});

app.use("/api/posts", postsRoutes);

module.exports = app;

CodePudding user response：

the problem is that you do not have an authorized user in mongodb atlas, check if you have the user authorized to use in that database, the database in which you need to access has an authorization. Take a look at accessing a new user from mongosh to access that db, or see if the username or password is correct. I hope it has served you, I will look to access more information if it goes wrong ;)

Edit: You will need to change the user "admin" to access this database

db.createUser({ user: "blogUser", pwd: "blogUserPwd", roles: [{ role: "dbAdmin", db: "blog" }, { role: "readWrite", db: "blog" } ]})

i ended up downgrading the mongoose version and it worked fine
