Invalid reuse object: must have both videoId and mediaId

Error message

Invalid reuse object: must have both videoId and mediaId

What it means

uploader.initialize() accepts an optional `reuse` object so the caller can attach the upload to an already-created Bunny video instead of creating a new one. When `reuse` is truthy but is missing either `videoId` or `mediaId` (the two identifiers the uploader needs to target the existing video), the constructor-time contract is broken and initialize() throws immediately before doing any network work. This is a caller-supplied-input validation error, not a network or auth failure.

Solutions

1. Fix the caller to pass both reuse.videoId and reuse.mediaId (non-empty strings) whenever reuse is provided.
2. If reuse cannot be fully populated, omit the reuse property entirely so initialize() falls back to journal/video-map lookup or creates a fresh Bunny video.
3. Inspect where the reuse object was built and log it; likely one field is undefined because the upstream API/storage shape changed.

Example fix

// before
await uploader.initialize({ projectId, sceneId, type, reuse: videoInfo });
// after
const reuse = videoInfo?.videoId && videoInfo?.mediaId ? { videoId: videoInfo.videoId, mediaId: videoInfo.mediaId } : undefined;
await uploader.initialize({ projectId, sceneId, type, reuse });

if (reuse && !(typeof reuse.videoId === 'string' && reuse.videoId && typeof reuse.mediaId === 'string' && reuse.mediaId)) {
  throw new TypeError('reuse must include both videoId and mediaId, or be omitted');
}

function isValidReuse(reuse) {
  return reuse == null || (typeof reuse.videoId === 'string' && reuse.videoId.length > 0 && typeof reuse.mediaId === 'string' && reuse.mediaId.length > 0);
}

try {
  await uploader.initialize({ projectId, sceneId, type, reuse });
} catch (err) {
  if (String(err?.message).includes('Invalid reuse object')) {
    // fall back to fresh/journal init
    await uploader.initialize({ projectId, sceneId, type });
  } else throw err;
}

When it happens

Trigger: Calling initialize({..., reuse}) where reuse is truthy but reuse.videoId or reuse.mediaId is undefined/null/empty string — e.g. reuse was built from an API response field that was absent, or a partially-hydrated object was passed in.

Common situations: Passing a stored video-map entry where only one of the two IDs survived serialization; destructuring a server response where the API changed shape and only videoId came back; passing `{}` or a truthy-but-incomplete placeholder to force reuse semantics.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
