[JS] Angular - Error when evaluating SSR module when importing zod from genkit

[markgoho]

Describe the bug
Trying to import { z } from 'genkit' on the server results in:

9:06:01 AM [vite] (ssr) Error when evaluating SSR module ./server.mjs: Cannot read properties of undefined (reading 'object')
      at eval (D:\GitHub\test-genkit\src\app\output-schema\menu-item-schema.ts:3:33)

I have a repo here that can be used to reproduce: https://github.com/markgoho/test-genkit

To Reproduce
Check out repo, npm install

Failure: in menu-item-schema.ts and genkit.ts replace z import statements with import { z } from 'genkit;`

Run: npx genkit start -- ng serve

Access localhost:4200 and see error both in browser (short error) and in terminal:

If you revert changes to import { z } from '@genkit-ai/core'; and restart the run command completely this now works as expected.

Expected behavior
Importing z from recommended source should work.

Screenshots
If applicable, add screenshots to help explain your problem.

Runtime (please complete the following information):

• OS: [e.g. Linux, MacOS] Windows 11
• Version [e.g. 22]

** Node version

• 22.14

Additional context
This obviously could be an issue with Angular, vite, ssr, etc. However, if this is a known issue, we might want to recommend the import { z } from '@genkit-ai/core'; path if users are using Angular SSR to avoid this issue.
