Error: Invalid source/target

[nglgzz]

Hello, I'm trying to run the project, but I can't seem to display relationships.

I cloned this repo, changed the credentials to Neo4j and run npm install & npm start. I tried a few queries besides the default one but I keep getting an alert saying Error: Invalid source or Error: Invalid target depending on the query. If on the query I don't return relationships it works fine, so I'm guessing it's a problem with those.

On Neo4j Browser I can render the same queries fine, any idea on what's the cause of this error?

Thank you, Angelo
