Troubleshooting YouTube Parsing Error: Extracting String from Array in Code Node

Hitting an error here where I can not do work with part of the youtube parsing node. Trying to just use "code" to grab the key I want but its throwing an error that it wants the variable to be a string when its an array. At a a loss for to do the extraction if something like this won't even work with code. Using the ai for this is not an option as the object can be fairly large and get cut off when passing directly to the next step
