**What version of Ajv are you using? Does the issue happen if you use the latest version?**

8.11.0, yes

**Your typescript code**

```typescript
import type { JSONSchemaType } from 'ajv';

type Level = 0 | 1 | 2;
interface ValidateConfig {
rules: Record;
}

export const schema: JSONSchemaType = {
type: 'object',
required: ['rules'],
properties: {
rules: {
type: 'object',
additionalProperties: {
type: [
{
type: 'number',
enum: [0, 1, 2],
},
{
type: 'array',
minItems: 1,
items: [
{

enum: [0, 1, 2],
},
{

```

**Typescript compiler error messages**

```
Type '{ type: "object"; required: "rules"[]; properties: { rules: { type: "object"; additionalProperties: { type: ({ type: string; enum: number[]; } | { type: string; minItems: number; items: ({ type: string; enum: number[]; } | { ...; })[]; })[]; }; }; }; }' is not assignable to type 'UncheckedJSONSchemaType'.
The types of 'properties.rules' are incompatible between these types.
Type '{ type: "object"; additionalProperties: { type: ({ type: string; enum: number[]; } | { type: string; minItems: number; items: ({ type: string; enum: number[]; } | { type: string; })[]; })[]; }; }' is not assignable to type '{ $ref: string; } | (UncheckedJSONSchemaType, false> & { const?: Record | undefined; enum?: readonly Record<...>[] | undefined; default?: Record<...> | undefined; })'.
Types of property 'additionalProperties' are incompatible.
Type '{ type: ({ type: string; enum: number[]; } | { type: string; minItems: number; items: ({ type: string; enum: number[]; } | { type: string; })[]; })[]; }' is not assignable to type 'boolean | UncheckedJSONSchemaType | undefined'.
Type '{ type: ({ type: string; enum: number[]; } | { type: string; minItems: number; items: ({ type: string; enum: number[]; } | { type: string; })[]; })[]; }' is not assignable to type '{ type: "array"; items: readonly [UncheckedJSONSchemaType & { const?: Level | undefined; enum?: readonly Level[] | undefined; default?: Level | undefined; }, UncheckedJSONSchemaType<...> & { ...; }] & { ...; }; minItems: 2; } & { ...; } & { ...; } & { ...; }'.
Type '{ type: ({ type: string; enum: number[]; } | { type: string; minItems: number; items: ({ type: string; enum: number[]; } | { type: string; })[]; })[]; }' is missing the following properties from type '{ type: "array"; items: readonly [UncheckedJSONSchemaType & { const?: Level | undefined; enum?: readonly Level[] | undefined; default?: Level | undefined; }, UncheckedJSONSchemaType<...> & { ...; }] & { ...; }; minItems: 2; }': items, minItems
