Zotero Does not Detect Date of YouTube Video
The generator could search for tag content starting with "Published on " (followed by MON, DD, YYYY where MON is the 3-letter month abbreviation)--tested using zbib.org 2019-07-08. If Zotero cannot run the ECMAScript, the date field can be obtained from the quoted string, embedded in the script, rather easily by searching for '"Published on ' and ending in '"' in a raw HTML code script tag since it is delivered not obtained via AJAX (there are no newlines in the actual script, not that newlines matter--I just used a formatter for demonstration purposes): https://pastebin.com/KgLcAw3a
"dateText":{"simpleText":"Published on Jul 9, 2019"}
