Good day, I am trying to integrate a mongoose database into my AdminJS project using Express.js. I have imported all the necessary packages, but when I run the server, I get an error saying that the module @adminjs/mongoose cannot be found. I’m not sure if it’s a compatibility issue, but I have tried uninstalling and reinstalling the package multiple times, and the error persists. If anyone can help me resolve this issue, I would greatly appreciate it. Below is the project code and the error messages:

Main file (app.ts):
(The Mongoose URL is stored in a .env file):

import express from 'express';
import AdminJS from 'adminjs';
import AdminJSExpress from '@adminjs/express';
import mongoose from 'mongoose';
import * as AdminJSMongoose from '@adminjs/mongoose';
import * as dotenv from 'dotenv';
import { PersonModel } from './models/personModel.js';
dotenv.config();

const port = process.env.PORT || 3000;

AdminJS.registerAdapter({ 
    Resource: AdminJSMongoose.Resource,
    Database: AdminJSMongoose.Database,
});

const start = async (): Promise<void> => {
  const app = express();

  await mongoose.connect(`${process.env.MONGO_URL}`);

  const admin = new AdminJS({
    resources: [
      {
        resource: PersonModel
      }
    ]
  });

  const adminRouter = AdminJSExpress.buildRouter(admin);

  app.use(admin.options.rootPath, adminRouter);

  console.log(`Starting server on port ${port}`);
  app.listen(port, () => {
    console.log(`AdminJS available at http://localhost:${port}${admin.options.rootPath}`);
  });
};

start();

Model schema file:

import { model, Schema } from 'mongoose';

export interface Person {
    name: string;
    age: number
};

export const PersonSchema = new Schema<Person>({
    name: { type: String, required: true },
    age: { type: Number, required: true }
});

export const PersonModel = model<Person>('Person', PersonSchema);

Error message when running the server:

import * as AdminJSMongoose from '@adminjs/mongoose';

I tried to install and import the @adminjs/mongoose package into my AdminJS project, as per the documentation, to integrate a Mongoose database with AdminJS. I expected the module to be recognized and allow me to register the Mongoose adapter in AdminJS, but instead, I got a TypeScript error indicating that the module couldn’t be found or its type declarations were missing. I tried reinstalling the package multiple times, but the issue persists.
