products.deleteMany()` buffering timed out after 10000ms

Hi i am trying to upload my products from my json file to the database. I am able to connect to the database however when i try to upload the products i am getting this error.

Error with data import MongooseError: Operation `products.deleteMany()` buffering timed out after 10000ms
    at Timeout.<anonymous> (C:\Users\nmajo\OneDrive\Desktop\Webapp2\node_modules\mongoose\lib\drivers\node-mongodb-native\collection.js:185:20)

This is the code i am using.

require("dotenv").config();
const productData = require("./data/products");
const connectDB = require("./config/database");
const Product = require("./models/Products");

 connectDB();

const importData = async () => {
  try {
    await Product.deleteMany({});

    await Product.insertMany(productData);

    console.log("Data Import Success");

    process.exit();
  } catch (error) {
    console.error("Error with data import", error);
    process.exit(1);
  }
};
importData();

When i remove the await on the Product.deleteMany and the Insert many, its saying products have been uploaded, however when i check the mongo db, there are no products. Does anyone have an idea on how i can fix this ?

Hi I also have a similar issue and nothing has worked for me so far (users.findOne in my case). One thing that I noticed is that when I search “buffering timed out after 10000ms” in stackoverflow pretty much all of the problems with the above phrasing came from December 2020 and January 2021 (also Feb 2021). So perhaps this is a mongoose problem caused by an update within that time period?

Seconded w/ @TerraAtgithub . I tried to deploy to Heroku many times yesterday but I kept encountering a buffering .find() 10000ms. Even when I’ve wrapped my mongoose.connect inside an async/await function I received a “Error: MongooseError: Cannot call posts.find() before initial connection is complete if bufferCommands = false. Make sure you await mongoose.connect() if you have bufferCommands = false.”

Have noticed few posts recently about the mongoose.connect buffering 10000ms issue within the past few months.
