Import error when importing libsodium-wrapper to a react-scripts-test unit test

Hello,

We've been working with libsodium-wrappers for a while, and it's an amazing library. We use it with functions in Node.js and React. Everything works fine when the libsodium-wrapper import is used within the app itself. However, we face some issues whenever we want to test anything that has a dependency on libsodium wrappers.

When I execute react-scripts test for the following code snippet.


import _sodium from 'libsodium-wrappers';

describe('sodium test', () => {
    it.only('test', async () => {
        await _sodium.ready;
        console.log('done');
        console.log(_sodium);
    });
});

I receive the following error

TypeError: Cannot read properties of undefined (reading 'sodium')

> 1 | import _sodium from 'libsodium-wrappers';
    | ^
  2 |
  3 | describe('useAuthTest', () => {
  4 |     beforeAll(async () => {});

It seems that there is a problem with importing the underlying sodium library. As I understand it, the asynchronous behavior of libsodium is the reason why you have to await with _sodium.ready in the first place. However, when executed within the unit test, the error occurs during the import process itself.

Do you have an idea how I could fix this issue?

Thanks for your help!
