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??

this appears in cmd window

  • Please post the actual text of errors (and format it using the options in the toolbar) rather than pictures. The images are unsearchable and normally hard to read. – hardillb Dec 21 '18 at 14:34

Node-RED is crashing because the node-red-contrib-sparql node is not properly catching and handling the error.

You need to open an issue against that specific node (which I can't find on flows.nodered.org)
