ESM module in Zod 2 beta causing runtime error

With Zod 2.0.0-beta.20:

With Zod 1.11, no error.

Only seems to happen when using the object type

// no crash
z.string();
z.date();
// crashes
z.object({});
z.object({
  id: z.string(),
});

Gonna re-open because the root problem here isn’t solved 😦

I removed the ESM module in zod@2.0.0-beta.21. If you upgrade your builds should work again.

I’ve also reproduced this issue. Now that I’m aware of this I’ll be able to guarantee ESM compatibility before trying to ship an ESM module again. It’s not trivial to fix so it’ll take some time. There are certain internal circular imports inside Zod’s source code that work fine with CommonJS modules but not with ESM.
