### Region

Australia

### Provide a description that is worded well enough to be understood

This is a single video release, not a series, so it shouldn't be trying to associate a series. Curiously the key *is* there, but it's null.

Base URL: `https://iview.abc.net.au/show/breaking-the-code-cyber-secrets-exposed`

If I run `yt-dlp` on the video URL from the html, it works: `https://iview.abc.net.au/show/breaking-the-code-cyber-secrets-exposed/video/NS2337H001S00`

This is the output of curl'ing the page:
[iview-page-output.html.gz](https://github.com/yt-dlp/yt-dlp/files/11646776/iview-page-output.html.gz)


### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
