Hello Racket friends:
Please, if possible: could you verify** if the youtube procedure in the very useful scribble-embedding package is working fine for you?**

In my installation (Racket v9.1, under Windows 10 and the current version of scribble-embedding package), the following code:

#lang scribble/manual
@require[scribble-embedding]
@title[#:style 'toc-hidden]{Testing @tt{scribble-embedding's} @tt{youtube} procedure}
@(youtube "https://www.youtube.com/embed/y1rOWZkALto")

Generates the following message:

Thank you very much in advance for your support on this issue.
Kind regards,
E. Comer

P. S.
(a) The google-form procedure, is working fine.
(b) As a reference, the youtube procedure (in scribble-embedding package) worked fine when I use it, the years 2022-2025.

Interesting!

I pasted the link

https://www.youtube.com/embed/y1rOWZkALto

into youtube and got the error.

But I now see that it works on Discourse.

Does this link work for you?

Thank you @soegaard , for your reply.

The link that you shared: "https://youtu.be/y1rOWZkALto" works fine, directly in my web browser.

I'm using as a reference the documentation for the scribble-embedding package, for example as in the file with link: scribble-embedding/scribblings/doc.scrbl at master · shriram/scribble-embedding · GitHub . Please see line 90 of the code, that corresponds in my local documentation to:

@(youtube " https://www.youtube.com/embed/43XaZEn2aLc ")

The problem is that (in my current installation,) the code above (line 90) generates the Error 153, at the HTML output of the associated scribble file.

Does the above line of code, works fine in your installation, using the scribble-embedding package?

Thank you very much for your support to solve this issue.

The link that you shared: "https://youtu.be/y1rOWZkALto" works fine, directly in my web browser.

Does it work in Scribble too?

If not, do you have a minimal, full Scribble we can use to debug?

Thank you @soegaard . The link "https://youtu.be/y1rOWZkALto" doesn't work under Scribble file:

A minimal Scribble file to produce the Error 153 is:

#lang scribble/manual
@require[scribble-embedding]
@(youtube "https://www.youtube.com/embed/43XaZEn2aLc")

Exploring this issue, I searched for the API changes for embedding a Youtube video, and found that the Error 153 was introduced in July 9, 2025. See the section with link: https://developers.google.com/youtube/iframe_api_reference#Revision_History

It seems that a HTTP Referer is now needed to be able to embed the YouTube Video: see for example the section with link: https://developers.google.com/youtube/terms/required-minimum-functionality#set-the-referer

Thank you again for your support to solve this problem.
Kind regards.
