error integrating on-demand's randomness feature

[0xMukesh]

hey there! i'm trying to integrate switchboard on-demand's randomness feature into my program. however, i'm encountering a strange error while running tests using the SDK, and i'm unsure how to resolve it.

the error message is as follows:

SyntaxError: Named export 'BN' not found. The requested module '@coral-xyz/anchor-30' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@coral-xyz/anchor-30';
const { BN, BorshAccountsCoder, utils } = pkg;

 ❯ tests/blet.test.ts:2:31
      1| import * as anchor from "@coral-xyz/anchor";
      2| import { AnchorUtils, Randomness, Queue } from "@switchboard-xyz/on-demand";
       |                               ^
      3| import { AnchorError, Program } from "@coral-xyz/anchor";
      4| import {

environment

1. testing framework - vitest
2. tsconfig - tsconfig.json
3. version of @switchboard-xyz/on-demand - v1.1.39 (latest)
4. node.js version - v22.3.0
5. package manager - pnpm v9.4.0

additional context

i think it's an issue related to how the package is bundled for CJS and ESM versions. any suggestions on how to resolve this would be greatly appreciated. thanks in advance!
