Error 0: Null primary key not allowed (for old link after deletion video)

Hello.

User deleted video that was awailable before in link: https://crimson-land.ru/videos/3900-v-muzhika-vselilos-zlo?from=listing
Now page display

Error 0: Null primary key not allowed

Is it OK? I expected to see 404 or something else.
P.S.: Before I turned ON some option in backend to try to display EasySocial's 404 error (if it possible) - can't remember exactley.

Thanks.
