Rich onebox parou de funcionar

Suporte

Notei que o onebox do meu site parou de funcionar no fórum Discourse que estou visitando. Ele funcionava na versão 1.8.x, mas agora o fórum foi atualizado para a 1.9.3 e meus oneboxes não estão mais funcionando. Verifiquei em try.discourse.org e o problema é o mesmo. As URLs dos oneboxes são assim:

Meu site retorna o seguinte oembed:

{
  "version":"1.0",
  "type":"rich",
  "width":600,
  "height":400,
  "title":"metr",
  "html":"<iframe src=\"https://metr.at/r/CF1go?oembed=true\" width=\"600\" height=\"400\"
    frameborder=\"0\"></iframe>",
  "provider_name":"metr.at",
  "provider_url":"https://metr.at"
}

Analisei o histórico de commits no repositório onebox do GitHub e encontrei 407fd0b8d6d41956e2400efc1918ace255aecd37 “Security: sandbox iframes, add rel to abs anchors”.

Será que meu onebox está falhando por causa do iframe e da segurança? Há algo que eu possa fazer?

I suspect that it is the iframe. Can you remove it?

I can not remove the iframe because the whole onebox is the iframe. If I remove it, there will be nothing left.

Discourse 1.8 uses onebox 1.8.12 and the commit you referenced was already part of that version. So, it must be something else. If your problem is caused by changes to the onebox gem, it should be one of the 79 commits: https://github.com/discourse/onebox/compare/e9164ee70186f87d2f2197de37a3a43f1274a060...master

I think I found the problem

https://github.com/discourse/discourse/commit/d6b22e6cc1b19a5279774fbe3a0138caca7918ea

do I understand right, the iframe will not be oneboxed unless whitelisted in the forum settings?

That’s exactly right :+1:
