 * Hi
 * Since 1.9.104, we’re getting the following php warning in our error log every
   time a visit occurs on a page containing an embedded YouTube video
 * `[15-Nov-2022 11:41:47 UTC] PHP Warning: Undefined array key "query" in /home/
   obfusc/public_html/wp-content/plugins/schema-and-structured-data-for-wp/admin_section/
   common-function.php on line 3653`
 * All pages continue to pass all markup tests without error. Thanks for looking.

 * I didn’t think to add, but the embedded YouTube videos are on WordPress Private
   Pages (password protected) created for customers. I’m unable to provide passwords
   to those pages. The site doesn’t have any embedded YouTube videos on any publicly
   accessibly pages. Thanks, Matt

 * Hi
 * Unfortunately on 1.9.105 the error is still being reported in our error log when
   visiting pages containing embedded YouTube videos. However, it now reports on
   line 3730 instead of 3653.

   Info: Apache
 * We’re embedding the YouTube videos within our pages using the WordPress Gutenberg
   block editor. The pages we embed videos on are all Password Protected, using 
   the native WordPress password protection. Some of the videos we embed are “Unlisted”
   on YouTube, but this doesn’t affect their URL’s. The pages that the videos are
   embedded in do not have a schema applied to them of any kind. The error notice
   I mentioned is being written to our /public_html/error_log whenever any page 
   containing embedded videos is visited. The videos don’t need to be interacted
   with to cause the error to be reported.
 * If there’s any other info you need that might be helpful please let me know. 
   Thanks again for looking.

 * [@magazine3](https://wordpress.org/support/users/magazine3/) This is now resolved.
   Issue detailed below
 * I discovered that one of the embeded YouTube video URL’s did not contain the 
   path /watch
 * So we had [https://youtu.be/UniQUEsTring](https://youtu.be/UniQUEsTring) (copied
   directly from the Share button on YouTube)
 * where this plugin actually needed:
 * [https://www.youtube.com/watch?v=UniQUEsTring](https://www.youtube.com/watch?v=UniQUEsTring)
   copied from the browser address bar
 * With the /watch path included, no errors are reported.

   queries do reach us and create a new topic.
