YouTube title value is doubled

[wooliet]

YouTube is returning two <title> elements in their HTML.

The "metascraper-youtube" sets the title value using:

$('title').text().replace(' - YouTube', '');

This returns both <title> elements and .text() appends them together.

If ":first" is added to the selector, only the first instance is returned.

$('title:first').text().replace(' - YouTube', '');

@wooliet Thanks for this; I tried to enter to a regular youtube URL (like this one https://www.youtube.com/watch?v=I-j_SMn8RRc) and I'm not seeing double title element.

How did you experience this? Can you point me to an online reproduction?

Using undici to make HTTP request with "User-Agent" header value set to "facebookexternalhit/1.1" (I don't remember where I found that solution, but otherwise it was really hit or missing getting anything useful back).

Here is one example of the response body, which contains <title> twice:
