PeerTube videos failing to embed via Gutenberg’s native embed block (oEmbed issue)

[Ben33]

Hello,

I’m encountering an issue embedding PeerTube videos into WordPress using Gutenberg’s native « embed » block. For a while now, when attempting to embed a PeerTube URL directly into Gutenberg, instead of displaying the video preview, Gutenberg shows an error stating « Error details » followed by an empty text field and a small lock icon below it.

I’ve already tested:

Multiple WordPress installations hosted in different environments.

Different browsers (Firefox and Chrome).

My self-hosted PeerTube instance and videos from peer.tube; both exhibit the same error.

Embedding the same PeerTube video using the manual iframe embed code in a custom HTML block works perfectly. Therefore, it seems the issue specifically affects Gutenberg’s built-in oEmbed functionality.

Has anyone experienced the same problem or could provide guidance on how to resolve this? Is there a known compatibility issue between recent Gutenberg/WordPress versions and PeerTube’s oEmbed implementation?

Thank you for your help!

Hi,

Does it work if you use the iframe provided by peertube? (instead of using oembed)

[Ben33]

yes it works well with the iframe code.

Can you share a wordpress page that use the oembed code so I see what’s the error?

Thanks, unfortunately wordpress sanitizes oembed output from peertube because it’s not in the internal whitelist: oEmbed – Advanced Administration Handbook | Developer.WordPress.org

I imagine that new security rules were introduced in the latest WordPress versions because embedding was working perfectly until recently. I’ll use iframe embedding for now as a workaround. I’ll check if it’s possible to request WordPress to whitelist PeerTube. Anyway, thank you for your help!
