Description

We're getting several 403 Client Error: Forbidden for url from the thumbnail endpoint at some Europeana images. Somehow someone has found these direct links and bypassed the death link validation. I deindexed the image with the identifier c4029005-12d5-4746-b264-781f0ee6eb31 but related images are also broken and sending events to Sentry.

Reproduction

1. Go to https://openverse.org/image/3bbdc183-0cea-44a5-b8c7-5242b9047bd9
2. Observe the placeholder "image not available" all over the page.
