Thank you! 😁 🙇

Are you saying you see them in the UI, but cannot access them via the API ?

Yes, that's it! As you can see in the video above ⤴ , I can see the remaining images (i.e., the images that haven't been deleted) both in the UI and physically on my disk storage, but cannot access them via the API (their leading URL does not exist).

(this would be strange as the UI is firing the same API requests to the back end)

And yes, this is strange but it's what I think! 😲 A few remaining images cannot be accessed via the API 🙁 .
I can't prove it easily, but while debugging my code snippet I listed all images accessible via the API and the remaining images are precisely those that do not appear in the API event list (I was not able to find them on the API).
In other words, as you can see in the picture below ⤵ , some of the events contain one JPEG image URL (and that's fine 👍 , I could retrieve each of those image URLs to delete the corresponding image from the server ✅ ), but unfortunately no event contains the URL that could have lead to the remaining few images.
Consequently, since the API doesn't seem to be aware of the existence of those images, those images cannot be accessed and hence cannot be deleted using the API. They simply remain on the server and are still visible in the UI after running my code.

This is why I wanted to ask if you ever encountered such a limitation of ClearML API with "events.get_task_events" service, or what we could do to avoid omitting those few remaining images on the server 🤔 .

Thank you again for your precious support! 🙏
