I have never come across a series or movie without that property, can you provide the name of the media so I can check it out further?

Series I encountered this issue with is Disney's Amphibia.

An easy fix would be creating an empty array variable, then wrapping the map function in a try/catch block. Then, when sending the update, send the variable created earlier.
