I have to connect to Sparql endpoint and query RDF via Node-red. I found an add-on node called "node-red-contrib-sparql" which enables that. I am able to install the node. I downloaded python and install required libraries for nodes to work. However, whenever I deploy the flow I lose connection to server and Node-red crushes. The error is written like below in cmd window. Is there someone who encountered the same problem or any other option in Node-red to query RDF data??

Well I see you opened an issue with the owner of the github page. That's probably the best way to get an answer.
