Recursive ref issue - Githubissues

Taking this file as an example:

import { O } from "ts-toolbelt"
import { FromSchema } from "json-schema-to-ts"

export const leafTypeSchema = {
  type: "string",
  enum: ["string", "number", "boolean"],
} as const
export type LeafType = FromSchema<typeof leafTypeSchema>

export const objTypeSchema = {
  type: "string",
  const: "object",
} as const
export type ObjType = FromSchema<typeof objTypeSchema>

export const leafSchema = {
  type: "object",
  additionalProperties: false,
  properties: {
    id: { type: "string", format: "uuid" },
    key: { type: "string" },
    type: leafTypeSchema,
    name: { type: "string" },
  },
  required: ["id", "key", "type", "name"],
} as const
export type Leaf = FromSchema<typeof leafSchema>

export const objSchema = {
  $id: "objSchema",
  type: "object",
  additionalProperties: false,
  properties: {
    id: { type: "string", format: "uuid" },
    key: { type: "string" },
    type: objTypeSchema,
    name: { type: "string" },
    fields: { type: "array", items: { anyOf: [{ $ref: "#" }, leafSchema] } },
  },
  required: ["id", "key", "type", "name", "fields"],
} as const
export type ObjRaw = FromSchema<typeof objSchema>

export const fieldTypeSchema = {
  anyOf: [leafTypeSchema, objTypeSchema],
} as const
export type FieldType = FromSchema<typeof fieldTypeSchema>

export const fieldSchema = {
  anyOf: [objSchema, leafSchema],
} as const
export type Field = Obj | Leaf

export type Obj = O.Update<ObjRaw, "fields", Array<Field>>

I'm seeing this: Type of property 'fields' circularly references itself in mapped type '{ id: { type: "primitive"; value: string; isSerialized: false; deserialized: never; }; key: { type: "primitive"; value: string; isSerialized: false; deserialized: never; }; type: { type: "const"; value: "object"; isSerialized: false; deserialized: never; }; name: { ...; }; fields: _$Array<...>; }'.

This was working prior to an update from 1.6 to latest (2.5.5). Recommendation on how to resolve?
