Add a customErrorMap to a .shape schema

[Stephane-Pires]

Hello,

I want to be able to customize remap ALL errors from a schema (to display them on the UI).

Basically I have :

// This schema represent the cat entity
// cat schema
export const catSchema = z.object({
  age: z.number(),
  weight: z.number(),
  home: z.string().min(1),
  friend: z.string().min(1),
});

// This schema represent the schema that will be used to validate the date on the backend (it's the schema for the database)
export const insertHouse = z.object({
	name: z.string(),
	cat: catSchema,
});

// This schema represent the schema that will be used to validate the form
export const houseFormSchema = z.object({
	name: insertHouse.shape.name.trim().max(255).min(1),
	cat: insertHouse.shape.catSchema,
});

const customErrorMap: z.ZodErrorMap = (error, ctx) => {
	/*
	This is where you override the various error codes
	*/
	switch (error.code) {
		case z.ZodIssueCode.invalid_type:
		case z.ZodIssueCode.invalid_literal:
		case z.ZodIssueCode.unrecognized_keys:
		case z.ZodIssueCode.invalid_union:
		case z.ZodIssueCode.invalid_union_discriminator:
		case z.ZodIssueCode.invalid_enum_value:
		case z.ZodIssueCode.invalid_arguments:
		case z.ZodIssueCode.invalid_return_type:
		case z.ZodIssueCode.invalid_date:
		case z.ZodIssueCode.invalid_string:
		case z.ZodIssueCode.too_small:
		case z.ZodIssueCode.too_big:
		case z.ZodIssueCode.invalid_intersection_types:
		case z.ZodIssueCode.not_multiple_of:
		case z.ZodIssueCode.not_finite:
		case z.ZodIssueCode.custom:
			return { message: `The cat has an error` };
	}
};

I want to map error from insertHouse.shape.catSchema, from houseFormSchema to use customErrorMap

So that each parsing error on insertHouse.shape.catSchema from houseFormSchema are changed to The cat has an error

AND I only want the houseFormSchema to be affected. I don't want to remap the error elsewhere.

Can someone point me to the documentation, (I already read the zoo documentation, about errors, but I'm not sure if what I want to do is feasible at all)

Thanks for reading/answering
See you
