Worker not bundling imported files

I am trying to load a Worker in the following way:

const url = new URL('./path/to/worker.ts', import.meta.url);
const worker = new Worker(url);

In the worker file I am trying to do an import:

import { someFunction } from './functions';

someFunction();

If I don’t provide { type: 'module' } to the Worker constructor, the import doesn’t get bundled with the worker and the following error is displayed in the console:

Uncaught SyntaxError: Cannot use import statement outside a module

If I do provide { type: 'module' } to the Worker constructor then it request the file without the extension: http://localhost:8080/functions which then returns a 404 due to the fact that a file without the extension doesn’t exist.

I would expect this to be bundled similar to the way that it is bundled when creating a webpage that uses imports as well where everything is in one file. Is there something I am doing wrong or is this a missing Webpack feature?

@debo07 don’t worry, it is in my TODO list, sorry for delay, a lot of tasks
