Your code has two issues that stop it from functioning properly:

1. You call upon the res variable after it has exited its scope.
2. You attempt to get your res object's shortcode property erroneously.

For issue number 1, there are a few ways to solve this, but the easiest would be to use a multi-line arrow function in order to keep the res variable in scope while you call console.log on it a second time.

For issue number 2, saying console.log(res[0].shortcode); will most likely cause a type error to be thrown, as no property 0 exists on your res variable, so calling res[0] will return undefined. Trying to get a property from an undefined object will result in a TypeError. Based on the shape of the object you posted above, this should properly get the shortcode property from your res object:

console.log(res.edge_owner_to_timeline_media.edges.Media[0].node.shortcode);

You can probably get this working by doing something like this:
