My code isn’t working. I think I’ve written it correctly. My code is saying that “mongoose” should be connected to a database. I’ve tried to rewrite the code a lot of times without getting an error, and I don’t know what’s wrong. Plz help.
require('dotenv').config();
const mongoose = require('mongoose');
// Connect to MongoDB using the URI from the .env file
mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true })
.then(() => {
console.log('MongoDB connected...');
// Test the connection by listing databases (optional)
mongoose.connection.db.admin().listDatabases((err, result) => {
if (err) {
console.error('Error listing databases:', err);
} else {
console.log('Databases:', result.databases);
}
});
})
.catch(err => console.log('MongoDB connection error:', err));
shows this error: MongoServerError: bad auth : authentication failed
could it be because of this: (node:755) [DEP0040] DeprecationWarning: The punycode module is deprecated. Please use a userland alternative instead.
I did what you said, but it kicks me out with the error: Invalid scheme, expected connection string to start with "mongodb://" or "mongodb+srv://"
even though I have monogodb and mongodb+srv://
It still kicks me out, with this error, MongoParseError: mongodb+srv URI cannot have port number
and this warning is still here, DeprecationWarning: The punycode module is deprecated. Please use a userland alternative instead.
On the Mongodb website, under Security select Database Access
On the line with your email address, under Actions, click EDIT
Under Authentication Method select Password
Under Password Authentication click Edit Password, then click Autogenerate Secure Password
Click the Copy button next to the previous button to copy the password.
Store it in a safe place.
Also under Security check in Network Access that your ip address is listed, and the status is active
Under Database click Clusters
Click on the Connect button.
Under Connect to your application select Drivers
Under 3. Add your connection string into your application code click the copy button on the far right (the icon looks like two pages).
Replace <db_password> with the password from earlier.
Paste that mongo+srv string into the .env file as the value for the MONGO_URI variable.
Good morning, @Teller. I did what you said(and added the username also because you didn’t say what to do with it) and then I get this error: MongoServerError: bad auth : Authentication failed.
I double checked to see if I did everything right, and I did.
What else should I do?
Near the top right of the MongoDb page there is an account icon.
Click on it then go to their forum using the link.
First search for the error message keywords to see if there are similar posts, and any solutions or advice provided. Or make a new post, giving as many details as possible, such as a description of the problem, and the error messages you received. Do not include your username or password.
We would like to see what you are writing, to verify it is the right setting?
And the same with any confidential data - give us an example always modifying confidential values with fake but similar ones to the ones you are using.
(The security level of the database configurations is usually very very picky and strict for all databases. It takes time to learn where the error is coming from. We all have been there… )
