fix: bump `zod` to fix use with Google APIs + `.literal()` #6609

gr2m · 2025-06-03T18:59:59Z

Background

Follow up to #6421.

One known issue is that zod v4's .toJSONSchema() does not set "type" for .literal() types, which causes problems with Google's APIs, see

Since the fix was now merged and released in zod, we are bumping the minimal zod version.

Summary

Bump zod to v3.25.49

Verification

I updated the example at examples/ai-core/src/generate-object/google-vertex.ts to use import { z } from 'zod/v4'; and name: z.literal('Lasagna'),. It currently fails on v5, but works with the patch in this pull request

examples/ai-core/src/generate-object/google-vertex.ts


 async function main() {
  const result = await generateObject({
    model: vertex('gemini-1.5-pro'),
    schema: z.object({
      recipe: z.object({
-        name: z.string(),
+        name: z.literal('Lasagna'),


I thought it wouldn't hurt to persist the change I used to verify the fix since to reduce the chance of future regressions.

Would a unit test make sense (since it's a fix, to prevent regressions)? i have some for zod3 to json conversions.

Would a unit test make sense (since it's a fix, to prevent regressions)?

good idea, added via 9346f21

+    },
+    "text": {
+      "const": "hello",
+      "type": "string",


This is the relevant line that was missing in generated JSON Schemas from zod v4 prior the bump of zod to 3.25.49.

+        "two",
+        "three",
+      ],
+      "type": "string",


This is a unit test for z.enum() which was fixed in [email protected], but we didn't add a unit test yet.
