I cloned the GitHub repository for the react.js tutorial, then I installed the dependencies.  
but I can't get the data from the database when I open the https:localhost:3000,  
and I have an error when I try to add data to the database, the error is showing at the console in the browser, and when I start Stardog server, an error is showing in the terminal, everything is in the screenshots which I uploaded. So how I can fix it, please?

Hi Kheder,

Can you DM me your project repo and stardog.log file? I'm not able to reproduce this error when I clone the stardog-react-example-app tutorial on my machine.

Best,  
Steve
