Swagger/OpenAPI file?

Can't provide the full file, but this is the relevant endpoint:

      "/api/v1/business/{customerId}/notifications":{

What version of external packages are you using(@tanstack-query, MSW, React, Vue, ...)

"react": "18.3.1",
"zod": "3.23.4",
"@tanstack/react-query": "5.56.2",

What steps can reproduce the bug?

1. Generate the api files
2. Check validation schema and model

Result:

export type GetNotifications200 = "TYPE1" | "TYPE2" | "TYPE3";

export type GetNotificationsQueryResponse = GetNotifications200;

export const getNotifications200Schema = z.array(
  z.enum(["TYPE1", "TYPE2", "TYPE3"])
) as unknown as ToZod<GetNotifications200>;

export const getNotificationsQueryResponseSchema = z.lazy(
  () => getNotifications200Schema
) as unknown as ToZod<GetNotificationsQueryResponse>;

The schemas are generated correctly, but then cast into a single element instead of an array

How often does this bug happen?

Every time

What is the expected behavior?

Schemas cast correctly to an array of GetNotifications200/GetNotificationsQueryResponse

Setting enumSuffix to an empty string will result in some issues in creating enums, best to not set that to enum or Kubb will override other values. I will add an error when an empty string is being used.
