After examining my connection, I received the following output:
// Establish a connection with Mongo
const promise = mongoose
.connect(db, {
useNewUrlParser: true,
useCreateIndex: true,
useUnifiedTopology: true,
useFindAndModify: false }) // Adding new mongo url parser
.then(() => console.log('MongoDB Connected...'))
.catch(err => console.log(err));
console.log(promise);
Here's what was logged:

The issue arises from having three models: post, user, and message, making it impossible to upload files using multer for messages or posts. The puzzling part is why this occurs. It doesn't seem to be linked to my cluster since another project on the same cluster with multiple databases has implemented similar features successfully.
