• pnpm v9.1.0
• ts-node v10.9.2
• nodemon v3.1.3

On Stack Overflow, I found a similar problem and solved it, but there is another problem where I can’t solve it or find it, I used a node project to run discord.js bot, but because of my imports I couldn’t run the code, the script used is “dev”, my package.json:

"scripts": {
    "dev": "nodemon --exec node --experimental-loader ts-node/esm src/middleware.ts",
    "knip": { "knip": "knip",
    "knip:fix": "knip --fix",
    "lint": "eslint . --ext .ts"
  },

code:

import { client, Next } from '@/app';
import { CheckBasicDiscordGuild, SubBuffer } from '@/components';

// Handle unhandled promise rejections and uncaught exceptions
process.on('unhandledRejection', SubBuffer);
process.on('uncaughtException', SubBuffer);

const BooleanParam = await CheckBasicDiscordGuild(client);

if (BooleanParam === true) Next(client);

tsconfig.json & tsconfig.paths.json:
