400 Bad Request for ITV

Hi, I'm trying to download https://www.itv.com/watch/mr-bates-vs-the-post-office/10a0469/10a0469a0001 from ITV. I'm in the UK so don't need a VPN and when I originally tried to download with my Homebrew install I just kept getting a timeout. I since found a closed issue raised for ITV saying to use the GitHub master code instead of the current release version. I uninstalled my Homebrew youtube-dl and cloned the repo. Once cloned I ran the command:

python -m youtube_dl 'https://www.itv.com/watch/mr-bates-vs-the-post-office/10a0469/10a0469a0001' --user-agent 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36' --referer 'https://www.itv.com/watch/mr-bates-vs-the-post-office/10a0469/10a0469a0001'

but I'm getting the error this error everytime:

python -m youtube_dl 'https://www.itv.com/watch/mr-bates-vs-the-post-office/10a0469/10a0469a0001' --user-agent 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36' --referer 'https://www.itv.com/watch/mr-bates-vs-the-post-office/10a0469/10a0469a0001' --verbose

I've never used Python before so I could be doing something wrong. Any advice or help with this would be really appreciated. Thanks
