WARNING: unable to extract OpenGraph title

[Buckaroos88]

Checklist

• I'm reporting a "Warning" message being displayed while using youtube-dl as requested by the program.
• I've verified that I'm running youtube-dl version 2019.08.13 (as shown in log)
• I've checked that all provided URLs are alive and playable in a browser
• I've checked that all URLs and arguments have no special characters
• I've searched the bugtracker for similar bug reports including closed ones (some are similar, but none were directly Facebook related "Warning" messages as far as I could tell).
• I've read bugs section in FAQ

PLEASE NOTE: youtube-dl extracted the best quality Facebook video as expected and the only reason I'm reporting this is because the "Warning" message requested I do so. I am very happy with the results!
