Error parsing TS config file

[gee4vee]

I have what I think is a pretty basic Jest config written in TS:

import type { InitialOptionsTsJest } from 'ts-jest';

const config: InitialOptionsTsJest = {
  extensionsToTreatAsEsm: ['.ts'],
  globals: {
    'ts-jest': { useESM: true }
  },
  moduleNameMapper: {
    '^(\\.{1,2}/.*)\\.js$': '$1'
  },
  testEnvironment: 'node',
  roots: ['src'],
  verbose: true,
  moduleFileExtensions: [
    'ts',
    'tsx',
    'js',
    'jsx',
    'json',
    'node'
  ]
};
export default config;

However, I get this:

> jest --coverage

Error: Jest: Failed to parse the TypeScript config file /Users/gvalenc/git/DevX/blueprint4ts/jest.config.ts
  Error: Must use import to load ES Module: /Users/gvalenc/git/DevX/blueprint4ts/jest.config.ts
require() of ES modules is not supported.
require() of /Users/gvalenc/git/DevX/blueprint4ts/jest.config.ts from /Users/gvalenc/git/DevX/blueprint4ts/node_modules/jest-config/build/readConfigFileAndSetRootDir.js is an ES module file as it is a .ts file whose nearest parent package.json contains "type": "module" which defines all .ts files in that package scope as ES modules.
Instead change the requiring code to use import(), or remove "type": "module" from /Users/gvalenc/git/DevX/blueprint4ts/package.json.

Can anyone give me some pointers what might be going on?
