Jest: cannot find module 'ai/rsc'

[mrasoahaingo]

Description

I tried to implement test using the generated app with

npx create-next-app@latest --example with-jest with-jest-app

Then I use the example here https://sdk.vercel.ai/docs/getting-started/nextjs-app-router

But when I launch

yarn test

I have this error

yarn test
 FAIL  app/page.test.tsx
  ● Test suite failed to run

    Cannot find module 'ai/rsc' from 'app/page.tsx'

    Require stack:
      app/page.tsx
      app/page.test.tsx

Getting the same issue here on plasmo

🔴 ERROR  | Build failed. To debug, run plasmo dev --verbose.
🔴 ERROR  | Failed to resolve 'ai/rsc' from './src/actions.tsx'
🔴 ERROR  | Cannot load file './rsc' from module 'ai'

Running plasmo@0.86.3, and tried ai version 3.0.0 to 3.0.2

I was able to work-around the module resolution via jest config update in moduleNameMapper:

moduleNameMapper: { ... '^ai/rsc$': '<rootDir>/node_modules/ai/rsc/dist', }
