typescript-fetch not working with requestBodies (reusable bodies)

usage of reusable (bodies https://swagger.io/docs/specification/describing-request-body/ section Reusable Bodies) doesn't generate a valid test suite and body models

definitions

paths:
  /v1/example
    post:
      tags:
        - example
      summary: create a new example
      requestBody:
        $ref: '#/components/requestBodies/CreateExample'
components:
  requestBodies:
    CreateExample:
      required: true
      content:
        application/json:
          schema:
            properties:
              name:
                type: string
            required:
              - name

Test suite errors

running npm test will produce errors like:

    api_test.spec.ts:212:21 - error TS2694: Namespace '"..."' has no exported member 'any'.

    212     const body: api.any = undefined

describe("ExampleApi", () => {
  test("v1ExamplePost", () => {
    const body: api.any = undefined // <------------------------------
    //...
  })
})

Missing body models

this is not an issue because library effectively works but doesn't use typescript types so every body use any as type

        /**
         * ...
         * @param {any} body 
         * ...
         */
        v1ExamplePost(body: any, id: string, options: any = {}): FetchArgs {

Start by reproducing the issue with the supplied reusable requestBody definition and run npm test. Inspect the generated api_test.spec.ts and the generated client method, then verify that the test suite no longer references api.any and that request bodies have usable TypeScript types.
