YouTube Embed Shows Error Message But Actually Works

[roundhill]

I was trying out Gutenberg (it's so cool! 🎉) and noticed an issue when trying to embed a YouTube video.

To Reproduce

1. Start a new post
2. Select + and then YouTube in the Embeds section.
3. Insert a YouTube url, I used https://www.youtube.com/watch?v=pdZQ98mWeto
4. You'll see this message Sorry, we could not embed that content.:

5. Publish the post. You'll see the video in the post just fine!

This would occur if there was an error in retrieving the embed result.

Can you look at your network tab and see what response you're receiving for the embed request?

It may be a 404 if you're running a version of WordPress that does not include the oEmbed proxy endpoint (>= WordPress 4.8).

I think you're exactly right @aduth:

{
    "code": "rest_no_route",
    "message": "No route was found matching the URL and request method",
    "data": {
        "status": 404
    }
}

Which version of WordPress are you running?

Which version of WordPress are you running?

Version 4.8: http://11f5306f.ngrok.io

Your site is not serving the REST API: http://11f5306f.ngrok.io/wp-json

Is this disabled, by you or your host?

(Try enabling permalinks if they're not already enabled)

(Try enabling permalinks if they're not already enabled)

This was the issue, the site had them set to plain. 👍 Seems like there should be a warning or something if that's the case.

@roundhill Depending on the web server, this isn't required. AFAIK this is more an issue in the web server breaking the REST API. It's not specific to Gutenberg.

It's not specific to Gutenberg.

Agreed, will close here and check if there's an issue on the REST API repo.
