Hi @Hamid_Ali,

Welcome to the MongoDB Community forums :sparkles:

It seems that the issue you’re facing could be due to the database not being connected. Could you please ensure the following:

  • Confirm that your database is connected, and your code is pointing to the correct URL.
  • Check if your mongoose.connect(...) code is loading properly.
  • Verify the structure of your code, especially if you’re running into issues when the mongoose.connect code is in a different file. Make sure to require that file in your main index.js file.

Additionally, as per the Mongoose documentation at https://mongoosejs.com/docs/connections.html. The model might be called before the connection is established.

To resolve this, consider using async/await with connect() or createConnection() or use .then(), as these functions return promises starting from Mongoose 5.

Here’s an example code snippet for your reference:

const dbconnect = async () => {
  await connect('<MongoDB_URI>');
  console.log("Connected to Database");
}

dbconnect()
  .catch((err) => console.error(err))

Make sure to adapt your code accordingly to incorporate these suggestions. I hope it helps!

Best regards,
Kushagra

i was facing the same problem , i didnt found anything on the internet , writing this so it might help someone , my connection string was correct i was using async await. everything was correct still i was getting the error. my problem was that , i was creating mongodb connection in different directory where the model was not present and trying to query in different directory . so it was to able to connect but not able to go to ready state. so i think better keep all your mongoose related file in one place and use only one connection file.
