I can’t add collection to mongodb database…. does anyone know why this is happening?

I use clerk and it works fine, I can see the users.

lib/database/index.tsx:

import mongoose from "mongoose";

const MONGODB_URI = process.env.MONGODB_URI;

let cached = (global as any).mongoose || { conn: null, promise: null };

export const connectToDatabase = async () => {
  if (cached.conn) return cached.conn;

  if (!MONGODB_URI) throw new Error("MONGODB_URI is missing");

  cached.promise =
    cached.promise ||
    mongoose.connect(MONGODB_URI, {
      dbName: "evently",
      bufferCommands: false,
    });

  cached.conn = await cached.promise;

  return cached.conn;
};

lib/database/user.model.ts:

import mongoose, { model, models, Schema } from "mongoose";

const UserSchema = new mongoose.Schema({
  clerkId: { type: String, required: true, unique: true },
  email: { type: String, required: true, unique: true },
  username: { type: String, required: true, unique: true },
  firstName: { type: String, required: true },
  lastName: { type: String, required: true },
  photo: { type: String, required: true },
});

const User = mongoose.models.User || mongoose.model("User", UserSchema);

export default User;

.env:

MONGODB_URI=mongodb+srv://patryk1:[email protected]/?retryWrites=true&w=majority&appName=Cluster0

Thx!
