That isn’t quite the entire code, but I’ll look once I can find the challenge link. It looks, at first glance, like you have misplaced / and " marks. There should be only one pair of quotes around the exact url you were given.
I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
