Jest with TypeScript weird import error: SyntaxError: Cannot use import statement outside a module

Im trying to configure an unit test for my website with Jest and I can't get it to work correctly. I've tried some of the solutions suggested by the ts-jest documentation but it still hasn't worked. Im not using Babel unless it's really necessary.

This is the link to the project: https://github.com/Kirarizinho02/AquaLink

This is what the jest.config.ts looks like:

import type { JestConfigWithTsJest } from 'ts-jest'
const config: JestConfigWithTsJest = {
  collectCoverage: true,
  coverageDirectory: 'coverage',
  coverageProvider: 'v8',
  preset: 'ts-jest/presets/default-esm',
  testPathIgnorePatterns: ['/node_modules/'],
  transform: {},
  moduleNameMapper: {
    '^(\\.{1,2}/.*)\\.js$': '$1'
  },
  testEnvironment: 'node'
}

export default config

This is the tsconfig.json:

{
  "files": [],
  "references": [
    {
      "path": "./tsconfig.app.json"
    },
    {
      "path": "./tsconfig.node.json"
    }
  ],
  "compilerOptions": {
    "jsx": "react",
    "isolatedModules": true,
    "esModuleInterop": true,
    "baseUrl": ".",
    "module": "NodeNext",
    "moduleResolution": "NodeNext",
    "target": "ESNext",
    "paths": {
      "@/*": ["./src/*"]
    }
  }
}

And this is the error:

    import { LoginUsers } from "@/components";
    ^^^^^^

    SyntaxError: Cannot use import statement outside a module

I've tried using testEnvironment: 'jsdom', but it didn't work.

I've tried changing my "type": "module" to "type": "commonjs" only to find the same error.
