This readme outlines the steps to take to reproduce an error I encountered while debugging issue saiichihashimoto/sanity-typed#394 (comment). Please mind that this does not reproduce a bug in the original package, but is just an explanation of the steps I took to encounter this specific error.

Node: v18.19.0 NPM: v10.2.3 PNPM: v8.11.0

Commit: 38e587a2a78e106a35c7f424f81f3c2af6058e04

• Set up a NPM Workspace to utilize local dependencies from @sanity-typed/types. Included only tsconfig, types, and utils for minimal setup.
• Built the types package using npm run build in the types folder, with tsup.config.ts from the original repository. (Note that the dist folder is not included in the repository, so to reproduce this step, you'll have to build the package yourself.)

Commit: 2147524f3b46a13efc0b1c2f3c47f2cb365b365a

• Created a new sanity-studio package running pnpm create sanity@latest.
• Installed necessary dependencies with pnpm.

Commit: 167576d18d943b03676cd70b9ec402fd7e5a9be9

• Installed the local types package in sanity-studio using pnpm add ../sanity-typed/types.
• Integrated the schema as suggested in the usage section of sanity-typed.
• Encountered an error while running the studio:

Uncaught error: The requested module '/@fs/Users/wannes/Projecten/Web/waspeer/sanity-typed-issue/sanity-typed/types/dist/index.js?t=1701806909825' does not provide an export named 'defineArrayMember'.

I triggered this error while debbugging the previous error. I just wanted to include it here to show how I encountered it.

• Temporarily reverted the imports back to sanity instead of @sanity-typed/types to remove the error.
• Added these lines for debugging:

import * as sanityTypedTypes from '@sanity-typed/types'
console.log('sanityTypedTypes', sanityTypedTypes)

• This resulted in the error I remembered and mentioned in the issue:

ReferenceError: module is not defined
    at http://localhost:3333/@fs/Users/wannes/Projecten/Web/waspeer/sanity-typed-issue/sanity-typed/types/dist/index.js:32:1

Commit: a2fb3d6bc6d0e8ad013e83ad2a484bef1a6f9566

• Built the types package to ESM using tsup. (To reproduce this step, run npm run build-esm in the types folder.)
• Changed the main and types fields in package.json to export the ESM files.
• This change resolved the import/export issue in the studio.
