POST API "Cannot read properties of undefined (reading 'findOne')"

[HSinghHira]

Hi there,

Thanks so much for sharing your code!

I'm currently on Day 7, and I ran into an error while using your code in authController.js for a POST API request.

The error message was:

{
  "success": false,
  "message": "Cannot read properties of undefined (reading 'findOne')"
}

I was able to fix the issue by making some changes:

  try {
    let user = await mongoose.connection
      .collection("users")
      .findOne({ username });
    if (user) {
      return res
        .status(400)
        .json({ success: false, message: "Username already in use" });
    }
    const securePassword = await bcrypt.hash(password, 10);

    const userModel = mongoose.model("User");
    user = new userModel({
      username,
      email,
      password: securePassword,
      accountType,
    });
    await user.save();

Could you please take a look and see if these changes are safe and follow best practices?

Really appreciate your work!
