Cannot read properties of undefined when I import another package

[hee-develop]

Hello, I'm trying to make my project to monorepo using yarn berry but something is wrong.
The module that I made and depend on another module, cannot run that cannot load 'another module'.

Directory is like this:

/
├ .yarn
│   └ cache
│      └ uuid-blahblah.zip
├ /module1
│   ├ index.js
│   └ package.json (including "uuid": "^version" in "dependencies")
├ .pnp.cjs
├ .yarnrc.yml
├ package.json
└ yarn.lock

And I wrote module1/index.ts like this:

import uuid from 'uuid';
const id = uuid.v4();
export default id;

I already installed VSCode plugins via yarn dlx @yarnpkg/sdks vscode and also installed ZipFS.
So when I see the code in VSCode, everything is clean and can go to uuid module to click 'uuid'.

But I noticed that module1 cannot load uuid module.

If I try to run module1, an error occur:
yarn workspace module1 node index.js

const id = uuid.v4();
               ^
TypeError: Cannot read properties of undefined (reading 'v4')

and also occur same error when using this module into another project:

/Users/me/module-test/node_modules/my-monorepo-module1/index.ts:13
const id = uuid.v4();
               ^
TypeError: Cannot read properties of undefined (reading 'v4')

I tried my best to solve it today, but I cannot find any answer..

Did I forgot any process? How can I use uuid module in module1?

Thanks to read my questions, and I would appreciate it if you could solve it :)

Sorry, this is a problem caused by my misunderstanding with uuid module..
uuid module doesn't offer default export.
It works now.
Sorry for useless question.
