Getting "Scheme Missing" Error with Wget

I wrote a little script that grabs a random wallpaper from the Desktoppr API and changes my desktop wallpaper to it:
#!/bin/bash
url=$(curl '(shuf -i 1-1000 -n 1) | jq ".response[].image.url" | sed $(shuf -i 1-20 -n 1)'!d') &&
wget "$url"
When I run the script, the final wget command fails with the error:
"": Scheme missing.
When I put the URL directly into the wget command, like so:
wget ""
... the command executes correctly and downloads the image, meaning that the error occurs because of some problem in the variable.
I think this might have something to do with the jq library that I am using to parse the JSON response from the Desktoprr API.

You need to remove the double quotes surrounding the URL, for example by using the -r option to jq:
url=$(curl '(shuf -i 1-1000 -n 1) | jq -r ".response[].image.url" | sed $(shuf -i 1-20 -n 1)'!d')
Currently the command actually results in
wget "\"""
