How to make scripts in a t3-stack app (with tsx and t3-env)?

I am trying to create a scripts folder to run things along my website and create tools, test things and all. I tried tsx with success, until I needed the env to be available (thus involving t3-env). I am currently trying to do a small script to test inserting things in my database:

import { db } from "~/server/db";
import { food } from "~/server/db/schema";

await db.insert(food).values({
  name: "Banana",
});

import { db } from "~/server/db";
import { food } from "~/server/db/schema";

await db.insert(food).values({
  name: "Banana",
});

Until now, I did scripts that did not involve resources from the app but right now I would like to connect to my database but I get this error:

:x: Invalid environment variables: {
  DATABASE_URL: [ 'Required' ],
  DATABASE_HOST: [ 'Required' ],
  DATABASE_USERNAME: [ 'Required' ],
  DATABASE_PASSWORD: [ 'Required' ],
}
.../node_modules/.pnpm/@t3-oss+env-nextjs@0.7.1_ophst5sms6obxk2veobtcst52a/node_modules/@t3-oss/core/index.ts:217
      throw new Error("Invalid environment variables");

:x: Invalid environment variables: {
  DATABASE_URL: [ 'Required' ],
  DATABASE_HOST: [ 'Required' ],
  DATABASE_USERNAME: [ 'Required' ],
  DATABASE_PASSWORD: [ 'Required' ],
}
.../node_modules/.pnpm/@t3-oss+env-nextjs@0.7.1_ophst5sms6obxk2veobtcst52a/node_modules/@t3-oss/core/index.ts:217
      throw new Error("Invalid environment variables");

For anyone looking for a solution... I managed to get it working after multiple try with the following setup: 1 - you will need the dotenv package 2 - my package.json look like this:

{
  "name": "project",
  "version": "0.1.0",
  "private": true,
  "type": "module",
  "scripts": {
    "build": "next build",
    [...]
    "tsx": "dotenv tsx",
    "dev": "next dev --turbo",
    "lint": "next lint",
    "start": "next start"
  },
[...]
}

{
  "name": "project",
  "version": "0.1.0",
  "private": true,
  "type": "module",
  "scripts": {
    "build": "next build",
    [...]
    "tsx": "dotenv tsx",
    "dev": "next dev --turbo",
    "lint": "next lint",
    "start": "next start"
  },
[...]
}

WIth this, I am able to run scripts with the following command: pnpm run tsx scripts/any-script.ts
