Json.items[0] throws an error. Can you help?

Question

JavaScript

Hello,
I'm making a bot for discord. I need help with this, when I request music from the bot, xs how to say "play music",
it only works on links, although it should also on names too. In the console it gives the following
" if (!json.items[0]) callback("3_-a9nVZYjk");"

The error says that the "items" field does not exist in the "json" object (in other words, items is undefined), so you can not access the element of the items field by index, because items does not exist (nothing good will come of it if Vasya tells Masha to get the ball with number 0 from the basket, which, according to him, is in front of her, but she, in fact, is not there, so there is nowhere to get the ball from).
