It usually happens when there is a blank reply. It happens sometimes with NSE itself as it gives blank data randomly. Just use a try, except module to handle it.

But be sure that the provided URL works properly i.e. will give the data you are looking for.

If You are having the problem, JSONDecodeEorr upgrade to the latest

pip3 install --upgrade nsepython

If the problem still persists, Let me know.
