🐛 Bug Report

Hi, I get an error when I try to import the presets.

● Validation Error:

  An unknown error occurred in ../../../../../jest.preset.js:

  No "exports" main defined in /Users/admin/Documents/custom_project/node_modules/jest-puppeteer/package.json
  Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in /Users/admin/Documents/custom_project/node_modules/jest-puppeteer/package.json

To Reproduce

Steps to reproduce the behavior:

file: jest.preset.js

const { merge } = require("lodash");
const nxPreset = require("@nrwl/jest/preset");
const puppeteer = require("jest-puppeteer");

module.exports = merge(nxPreset, puppeteer);

Do you know how I can solve my issue please, I feel like I am the only one with this issue

I'm running into the same issue. I combine two Jest presets (jest-puppeteer and es-jest) which was working under version 7 but is broken under version 8 (see my combined preset):

import esPreset from "es-jest/jest-preset.js";
import puppeteerPreset from "jest-puppeteer/jest-preset.js";

export default {
  ...puppeteerPreset,
  ...esPreset,
};

This now results in the following error:

Package subpath './jest-preset.js' is not defined by "exports" in /path/to/github-release-action/github-release-action/node_modules/jest-puppeteer/package.json imported from /path/to/github-release-action/github-release-action/jest.preset.js

You can see this error on the GitHub Actions build from Dependabot attempting to bump jest-puppeteer on my repo: https://github.com/eloquent/github-release-action/actions/runs/4343222488/jobs/7585002111#step:5:12
