I'm getting a response from an API, I'm interested only in one of the link that returns. I have been using for a while
["data"]["tasks"]["0"]["result"]["files"]["0"]["url"]
to get the URL but it seems the API has changed and now the "result" it changes the position 0 in every call...

I would like to always extract only the link:
https://storage.cloudconvert.com/tasks/somethinglink.pdf
which position can change as mentioned before... The link always start with https://storage.cloudconvert.com
I have been using this for a while to access the first object in the array
["data"]["tasks"]["0"]["result"]["files"]["0"]["url"]
but it doesn't seem to work if the link it's in a different position...

This code extracts all values as strings, then finds the one with the necessary prefix:
