Bug: references to nested properties in schemas generate invalid types

[avaly]

Description

The generated types in a parameters entry which references a nested property from a schemas entry is generating an invalid type.

Name	Version
openapi-typescript	7.0.1
Node.js	18.16.1
OS + version	Ubuntu 22.04

Reproduction

Generate types for the following OpenAPI schema:

openapi: "3.0"
info:
  title: test
  version: "1.0"
servers:
  - url: https://example.com
security: []
paths:
  /endpoint:
    get:
      description: Test
      summary: Test
      parameters:
        - $ref: "#/components/parameters/direct"
        - $ref: "#/components/parameters/nested"
      responses:
        200:
          description: '200'
          content:
            application/json:
              schema:
                type: string
components:
  parameters:
    direct:
      in: query
      name: direct
      schema:
        $ref: "#/components/schemas/aaa"
    nested:
      in: query
      name: nested
      schema:
        $ref: "#/components/schemas/bbb/properties/ccc"
  schemas:
    aaa:
      type: string
    bbb:
      type: object
      properties:
        ccc:
          type: number

Expected result

export interface components {
    schemas: {
        aaa: string;
        bbb: {
            ccc?: number;
        };
    };
    responses: never;
    parameters: {
        direct: components["schemas"]["aaa"];
        nested: components["schemas"]["bbb"]["ccc"];
    };
    requestBodies: never;
    headers: never;
    pathItems: never;
}

Actual result

export interface components {
    schemas: {
        aaa: string;
        bbb: {
            ccc?: number;
        };
    };
    responses: never;
    parameters: {
        direct: components["schemas"]["aaa"];
        nested: components["schemas"]["bbb"]["properties"]["ccc"];
    };
    requestBodies: never;
    headers: never;
    pathItems: never;
}

Notice the extra ["properties"] here, which makes the type for the nested property invalid.

Checklist

• My OpenAPI schema passes the Redocly validator (npx @redocly/cli@latest lint)
• I’m willing to open a PR (see CONTRIBUTING.md)
