Problem Install and Set Up Mongoose

Backend Development

I have followed the tutorial properly but this is what I got after the instructions

Your app is listening on port 3000
(node:2372) [DEP0170] DeprecationWarning: The URL mongodb://<user>:<password>@<database>-cluster-shard-00-00.jcsnu.mongodb.net:27017,<database>-cluster-shard-00-01.jcsnu.mongodb.net:27017,<database>-cluster-shard-00-02.jcsnu.mongodb.net:27017/?authSource=admin&replicaSet=atlas-96ixrx-shard-0&retryWrites=true&w=majority&ssl=true is invalid. Future versions of Node.js will throw an error.
(Use `node --trace-deprecation ...` to show where the warning was created)

I asked on chatgpt, and chatgpt suggested me to install mongoose@latest, after I installed the package.json mongoose dependency
changed from "mongoose": "^5.11.15" to "mongoose": "^8.9.3"

And when I run it, I get a different error

(node:2794) [MONGODB DRIVER] Warning: useNewUrlParser is a deprecated option: useNewUrlParser has no effect since Node.js Driver version 4.0.0 and will be removed in the next major version
(Use `node --trace-warnings ...` to show where the warning was created)
(node:2794) [MONGODB DRIVER] Warning: useUnifiedTopology is a deprecated option: useUnifiedTopology has no effect since Node.js Driver version 4.0.0 and will be removed in the next major version
Your app is listening on port 3000

And I still can’t solve the problem

Then I changed
mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true })
to
mongoose.connect(process.env.MONGO_URI)

and no error appeared

Do not update the dependencies and just ignore the deprecation warning. Deprecation warnings are not related to any test failing. Start over with a fresh boilerplate.

We need to see all your code. Post a repo or share the workspace as outlined on the challenge page.

Edit: You are not submitting the correct URL. It should be the one from the preview window, it starts with the port number.

thank you very much, i reverted the dependency version and entered the correct url and it worked
