Hello.
Some time ago I noticed a problem when adding a Youtube video post via postbox.
The problem does not seem to have any particular relevance - it will happen from time to time.
Then the video in the post is empty and can not be played (screenshot below).

In the database, such an entry looks like this:

I noticed that the problem most often occurs when I add a long comment to the video and between the insertion of the video link and using the "Post" button, it takes several minutes. However, this also happens when the video is added immediately, but in another time everything works fine.
How can this be solved?
Regards.
