`unable to retrieve user data from MongoDB due to a client-side buffering issue

Hello, I've been working with the mongo database and encountering an issue while trying to save my files into it. Here is the error click here to view

https://i.sstatic.net/jaQ7x.png

While using MongoClient.connect('mongodb://localhost:27017/database', {useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true }), I'm faced with this error message:
        .then(client => {
            console.log('Mongo Connected!!!');
            const db = client.db('database');
            const collection = db.collection('files');
            app.locals.fileCollection = collection;
        });

Any assistance would be greatly appreciated.

Answer №1

Issue: Attempting to query MongoDB before establishing a connection to the database.

Reference: https://mongoosejs.com/docs/connections.html#buffering

Mongoose allows immediate use of models without waiting for the connection to MongoDB to be established.

The internal buffering of model function calls by mongoose can be convenient but may lead to confusion. Mongoose does not throw errors by default if a model is used without connecting.

Solution: Ensure that mongoose has connected before initiating any db queries.
