ZOD

I want the final response of the API to look something like this:

{
  "user": {
      "email": string,
      "name": string,
  },
  "parent": { "email": string, "name": string } | null
}

{
  "user": {
      "email": string,
      "name": string,
  },
  "parent": { "email": string, "name": string } | null
}

So the parent can be nullable, I define my schema like this:

export const getUserByIdResponseSchema = z.object({
  user: z.object(userCore),
  parent: z.object(userCore).nullable(),
});

export const getUserByIdResponseSchema = z.object({
  user: z.object(userCore),
  parent: z.object(userCore).nullable(),
});

When the parent is null, it gets returned null like normal, but when there is actually a parent, this is the fastify error I'm getting. Any idea on how to fix this?

posting the userCore definition would be helpful

@sturlen userCore is just the email and name that were mentioned above. Here is the code:

const userCore = {
  email: z
    .string({
      required_error: "Email is required",
      invalid_type_error: "Email must be a string",
    })
    .email(),
  name: z.string({
    required_error: "Name is required",
    invalid_type_error: "Name must be a string",
  }),
};

const userCore = {
  email: z
    .string({
      required_error: "Email is required",
      invalid_type_error: "Email must be a string",
    })
    .email(),
  name: z.string({
    required_error: "Name is required",
    invalid_type_error: "Name must be a string",
  }),
};

if you can get the actual ZodError it should tell you exactly what it doesnt like
