Drive resumable init failed: ${initRes.status} ${errBody}

Error message

Drive resumable init failed: ${initRes.status} ${errBody}

What it means

The resumable upload session initialization POST to the Drive upload endpoint returned a non-OK status. Thrown in uploadResumable before any bytes are sent; causes include an invalid/expired token, bad metadata (invalid parent folderId or filename), or X-Upload-Content-Length/type inconsistent with the blob.

Solutions

1. Read the status and errBody for the Drive error reason
2. Refresh the OAuth token on 401/403 and retry the upload
3. Validate metadata: folderId exists, fileName sanitized and non-empty
4. Retry with backoff on 429/5xx; fail fast on 4xx client errors
