Images no longer accessible due to deleted upstream source

Hi, taking a look at the repository, I found that all images that were previously displayed through GitHub’s Camo proxy are no longer accessible (you can directly see it the repo, but here's the curl request for more details) .

curl -i https://camo.githubusercontent.com/28027a8dc22602b76d8c284ef94a3734d9cebcc3a5401faa4791b93eb6bced47/68747470733a2f2f636c6f75642d3162326676783866632d6861636b2d636c75622d626f742e76657263656c2e6170702f30636f7665722e706e67

Invalid upstream response (410)

As you can see, I get a 502 error from the proxy telling us the reason in the response body: a "410 Invalid upstream response" message.

After checking the original image source (decoded from the Camo URL, since the format is https://camo.githubusercontent.com/<hash>/<encoded-original-url>), we find the original url:

https://cloud-1b2fvx8fc-hack-club-bot.vercel.app/0cover.png

When accessing via the browser we see Vercel's message:

410: GONE
Code: GONE

Which means the Vercel host containing the served images was deleted / disabled by someone with access to Vercel configuration, so Camo can’t retrieve or serve the images anymore.

Any solutions / anyone with the right permissions can look into this please ?

Also, this can be helpful: from Vercel docs, deleted deployments can be restored, but it has to be done within 30 days of deletion.
