I'm attempting to pull the complete set of uploaded videos for a given YouTube channel using the YouTube Data v3 API (more specifically, using the Python client). I'm following the steps outlined in this Google tutorial. I'm also using authenticated requests.
When I follow this process, I've noticed that for some YouTube channels, not all video IDs are returned from the playlistItems.list method (when compared to the full list of videos available in YouTube Studio).
I've analysed the missing videos and can't see any reason why they would be omitted - they're publicly available and aren't restricted to a certain region/age group. I'm also correctly paginating through the responses.
Another strange observation is that when I request the information related to one of these missing videos using the videos.list method, the API returns the relevant data. So there seems to be some discrepancy between the data that feeds the playlistItems.list method and the videos.list method.
Has anyone observed something similar? If so, are there any workarounds? Or is it a known bug/limitation with the YouTube Data v3 API?
