Need to Get Attraction URL form Ticketmaster

I need to get the url for the first attraction from a list of json events. I am NOT getting anything. I have attached my blocks and a sample of the json results. The variable is set to “Artist”.
Thanks.

If the JSON data is loaded into the application, but you cannot get the value of the field, it means that the path to it is incorrect. How to find the right way? Sequentially get all the nodes - first the root node. If the data is displayed correctly, create a path to the next nested node and so on until you get the node you need.
