I'm not sure if here is the proper place to put this issue, if it's not please point me to the right place.

I'm using "mercadopago": "^2.0.0" and I'm getting errors using a simple node server:
Here's the full relevant code:

import express from "express";
import MercadoPago, { Payment } from "mercadopago";
import * as dotenv from "dotenv";

dotenv.config();

const app = express();

// Configure MercadoPago with your access token
console.log(process.env.MERCADO_PAGO_ACCESS_TOKEN);
const client = new MercadoPago({
  accessToken: process.env.MERCADO_PAGO_ACCESS_TOKEN,
});

package.json:

{
  "name": "mp-integration",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "dotenv": "^16.3.1",
    "express": "^4.18.2",
    "mercadopago": "^2.0.0"
  }
}

And I get this error:
**const client = new MercadoPago({
^

TypeError: MercadoPago is not a constructor**

I got this error in different environments.
The example above was using node v16.19.0

I also got this error when deploying my app on Vercel.
The same thing happened when trying to deploy on Koyeb.
That's why I decided to make this as simple as possible and build a simple node with express API to use MercadoPago, but it doesn't work.
The image below shows the full error on Vercel when I try to call a function that uses Mercadopago.
Vercel is using node version 18.x

If you need any other info, just let me know and I'll be happy to provide it.

Again, sorry if this isn't the right place, just let me know so I can put it somewhere else. I just put it here because it seems related with the new release.

Good afternoon @DaviRolim, thanks for reaching out to us!
There really was an inconsistency to the examples added on github, for vanilla javascript integration.
To create your integration correctly with javascript, it is necessary to add the .default at the end of MercadoPago
Eg.

import MercadoPago from 'MercadoPago'
...
const client = new MercadoPago.default({
  accessToken: process.env.MERCADO_PAGO_ACCESS_TOKEN,
});

This happens because the bundle is built and delivered using commonjs.

To improve the experience In this case, we released an new patch version on SDK 2.0.1
now you can import named, the module is called MercadoPagoConfig
Eg.

import { MercadoPagoConfig } from 'MercadoPago'
...
const client = new MercadoPagoConfig({
  accessToken: process.env.MERCADO_PAGO_ACCESS_TOKEN,
});

This way it is not necessary to add .default at the end of the module, this makes the way of using the module more natural.
Feel free to choose the best form of integration for you.

Lucas.
