zod: Is it possible to use custom openapi attributes?

[alexcupertme]

I want to use custom openapi attributes to use them in zod schema to pass them as error messages to my schema, e.g.:

components:
  schemas:
    User:
      type: object
      properties:
        email:
          type: string
          format: email
          x-error-message: "Invalid email format"

Turns into:

email: z.string().email({ message: "Invalid email format" })

How to do that in general? Maybe kubb already had this feature with error messges?

@alexcupertme For that you can use https://www.kubb.dev/plugins/plugin-zod/#mapper

mapper: {
          email: 'z.string().email({ message: "Invalid email format" }),
        },

@stijnvanhulle Thank you! This feature is really helpful. But can i rely specifically on the x-error-message property, not hard-coding the output?
