Getting a value from an array

wondering if anyone can help with this scenario, as I am kind of struggling with it.

Trying to return the following: {{2.array.data.values.channel_specific.default.images_products}}, and want to use the key (step in tool6) to find this.

blueprint (1).json (81.9 KB)

Kind of looks like this, step 8 is where I would like to search the array and find with the key.

key if def aval, but just cant figure out the logic. the item is an array as well, which I need to keep as an array so I can return it to another field.
