Oh it´s working right now.

Thanks :D

[spenserblack]

I didn't actually do anything 😆
I think this might need to be investigated to at least return a better error, because something is sporadically failing. Maybe it's the GitHub token's rate limit 🤔

Probably the cause is the GitHub token rate limit. Can you come up with any solution?

[JhonnyLusonode]

If it´s Github token then I don´t think you can find a solution for that unfortunately... (Pls correct me if i´m wrong)

[ryo-ma]

One way to solve this is to use Github tokens from multiple accounts to distribute the load. Or if it fails, there is a way to retry with another Token.
But it's a gray method.

For now, I think all that's needed is a better error message. GitHub has an API for checking the number of available requests: /rate_limit. This is a special API that will not reduce your rate limit when you use it. I think something as simple as

if (remaining < requiredRequestAmount) {
  return ErrorImageResponse; // "We cannot display <username>'s trophies right now"
}

Long term, images could be cached, but I don't think that's possible with Vercel alone. Some other tool or service would be needed.

Having this issue again!

Not perfect, but greatly improves downtime.
