Must use import to load ES Module

[jessegeens]

I'm likely doing something wrong when importing solid-auth-fetcher, but I'm not sure what. I have included a relevant code snipper below:

Describe the bug
Trying to run example code from server.ts results in node crashing with the error: Must use import to load ES Module: /home/jesse/.../node_modules/node-fetch/src/index.js

To Reproduce
Put the following code snippet in a typescript file, and then run it with node:

import {getAuthFetcher, getNodeSolidServerCookie} from "solid-auth-fetcher";

async handleRequest(request: Request) {
    let serverRoot = this.configMgr.getRootConfig().serverRoot;
    let userPrefs = request.userPreferences;
    let appOrigin = request.from;
    const cookie = await getNodeSolidServerCookie(
      serverRoot,
      userPrefs.username,
      userPrefs.password
    );
    if (!cookie) {
      throw new AuthenticationError(
        `Could not sign in with given credentials for user ${userPrefs.username}`
      );
    }
    const fetcher = await getAuthFetcher(serverRoot, cookie, appOrigin);
    const result = await fetcher.fetch(request.resource);
  }

Expected behavior
The code to run without throwing a fatal error

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /home/jesse/Documents/Thesis/master-thesis-jesse-geens/node_modules/node-fetch/src/index.js
require() of ES modules is not supported.
require() of /home/jesse/Documents/Thesis/master-thesis-jesse-geens/node_modules/node-fetch/src/index.js from /home/jesse/Documents/Thesis/master-thesis-jesse-geens/node_modules/solid-auth-fetcher/dist/obtainAuthHeaders.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /home/jesse/Documents/Thesis/master-thesis-jesse-geens/node_modules/node-fetch/package.json.

Changing const node_fetch_1 = __importDefault(require("node-fetch"));
to const node_fetch_1 = __importDefault(import("node-fetch"));
seems to solve the issue
