mong db connect error

// for mongodb atlas
mongoose.connect(
  "mongodb+srv://:@cluster0.88kbv.mongodb.net/?retryWrites=true&w=majority",
  {
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useCreateIndex: true,
    useFindAndModify: false,
  }
);

Here is what the above code is Doing:
1. We are importing mongoose from the mongoose package.
2. We are connecting to the database using the connect() method.
3. We are passing the connection string as the first argument to the connect() method.
4. We are passing an object as the second argument to the connect() method.
5. The object contains the following keys:
a. useNewUrlParser: This key is used to remove a deprecation warning when connecting to the database.
b. useUnifiedTopology: This key is also used to remove a deprecation warning when connecting to the database.
c. useCreateIndex: This key is used to remove a deprecation warning when creating an index.
d. useFindAndModify: This key is used to remove a deprecation warning when updating a document.
