`AdVideo` fields are incorrect

[mrowles]

Which SDK version are you using?

18.0.4

What's the issue?

The AdVideo class suggests only 3 fields are available:

export default class AdVideo extends AbstractCrudObject {
    static get Fields(): Readonly<{
        filepath: "filepath"; // <-- undefined
        id: "id";
        slideshow_spec: "slideshow_spec"; // <-- undefined
    }>;
   ...

The FB API documentation is all over the shop, but this API in particular is rife with mistakes.

❌ The documentation for Ads Api -> Get Ad Videos: https://developers.facebook.com/docs/marketing-api/reference/ad-account/advideos/

✅ The documentation for Video: https://developers.facebook.com/docs/graph-api/reference/video/

Steps/Sample code to reproduce the issue

import {
  AdAccount,
  AdVideo,
  FacebookAdsApi,
} from 'facebook-nodejs-business-sdk';

FacebookAdsApi.init(...)
const account = new AdAccount(...);
const videos = await account.getAdVideos([
  AdVideo.Field.filepath,
  AdVideo.Field.id,
  AdVideo.Field.slideshow_spec,
]);

Observed Results:

The fields are missing a whole bunch described in the above documentation.

Expected Results:

This is what we can actually get in terms of fields:

import {
  AdAccount,
  AdVideo,
  FacebookAdsApi,
} from 'facebook-nodejs-business-sdk';

FacebookAdsApi.init(...)
const account = new AdAccount(...);
const videos = await account.getAdVideos([
  AdVideo.Field.filepath,
  AdVideo.Field.id,
  AdVideo.Field.slideshow_spec,
]);

const videos = await this.account.getAdVideos([
