Problem with ez.dateOut() in workspace environment

[JonathanCabezas]

I have a file containing:

export const productPriceSchema = z
  .object({
    price: z.number(),
    date: ez.dateOut(),
  })

I have the following endpoint importing the schema:

export const getProductPricesEndpoint = routeFactory
  .addMiddleware(authMiddleware(Permission.Read, Modules.Product))
  .build({
    method: "get",
    tag: "product",
    description: "Get all the product prices.",
    input: emptySchema,
    output: z.object({ items: z.array(productPriceSchema) }),
    handler: async () => {
      const items = await getProductPrices();

      return { items };
    },
  });

I get the following error:

DocumentationError: Using z.date() within output schema is forbidden. Please use ez.dateOut() instead. Check out the documentation for details.
Caused by response schema of an Endpoint assigned to GET method of /api/product/unit/prices path.

If I inline the schema instead of importing it, it works fine.

I don't think this is related, but the import is done from another package (I have a monorepo structure).

I already had this issue before, and it disappeared I don't know why.

I tried with Bun and tsx runtimes, getting the same error.

What are the versions of

• express-zod-api
• typescript
• and Node

@JonathanCabezas ?

[RobinTail]

Yeah, you know, it's strange, because I also managed to run it using bun:

https://github.com/RobinTail/express-zod-api/actions/runs/10759041666/job/29835239011

Exact same versions. And it works without any issues, @JonathanCabezas
Perhaps the issues is something else.

[RobinTail]

What I can tell you for sure is that this line must be executed:

express-zod-api/src/index.ts

Line 1 in 975e379

import "./zod-plugin";

it runs the code that makes the difference between z.date() and z.dateOut().

Try to ensure import "express-zod-api" in the beginning of your entry file, @JonathanCabezas

Also I had the same problem with tsx.

There is no Node version,

, and because you don't have Node.js installed, only bun, I'm not sure how exactly it works in your case.

This is not an MVCE, and I'm really unsure what's causing this problem so it's hard to produce one...
I only shared the one endpoint causing the issue. If I replace the imported schema with an inlined version, it works but another endpoint using ez.dateOut() is raising the same error.

Adding import "express-zod-api" to the beginning of my entry file didn't fix it.

I'll try to mess around with tsx.

Also, it stopped working after a specific commit so I'll try to narrow it down there, but I didn't change anything related to endpoints/schemas there.

[JonathanCabezas]

tsx runs my globally installed Node.js which is v22.0.0, still getting the error.

[JonathanCabezas]

@RobinTail So this had nothing to do with bun.

I had indeed 2 versions of typescript between my back and my packages/shared workspace. This was causing express-zod-api to be bundled twice at 2 different locations by pnpm. I don't know exactly how, but this broke something in express-zod-api.

apps/back:
   dependencies:
     express-zod-api:
       specifier: ^20.7.1
       version: 20.7.1(@types/express@4.17.21)(@types/http-errors@2.0.4)(compression@1.7.4)(express@4.19.2)(http-errors@2.0.0)(typescript@5.2.2)(zod@3.23.8)

packages/shared:
   dependencies:
     express-zod-api:
       specifier: ^20.7.1
       version: 20.7.1(@types/express@4.17.21)(@types/http-errors@2.0.4)(compression@1.7.4)(express@4.19.2)(http-errors@2.0.0)(typescript@5.4.5)(zod@3.23.8)

I fixed it by removing the typescript dependency from both projects and using a global dependency at my monorepo root.

[RobinTail]

Wow, that's great that you managed to figure that out.
Thank you for letting me know, @JonathanCabezas !

[RobinTail]

I think it could also had been two versions of zod installed.

[JonathanCabezas]

Could be indeed.

You're welcome :)
