We are working on a backend with Fastify, declaring schemas with Typebox and generating OpenApi definitions with Fastify Swagger
We are facing some problems with enums or similar during docs generation

Let’s say we declare a typebox enumerator in one of the following ways

export const ProviderType = Type.Union([
  Type.Literal("sms"),
  Type.Literal("email"),
]);

//OR

enum Providers {
  SMS = "sms",
  EMAIL = "email",
}

export const ProviderType = Type.Enum(Providers);

When the open api docs are generated we get this

- schema:
    anyOf:
        - type: string
          enum:
              - sms
        - type: string
          enum:
              - email

That is not what we expect, but something like

schema:
    type: string
    enum: [sms, email]

Otherwise, the places where the enum is used are not correctly rendered by the various packages.

Did you already face this problem?
