Starting a node server backend with b2b API

I’m using

b2bapis.b2bcontrol.startNodeServer(“server.js”, “myserver”, onSuccess, onFailure);

to start a backend server to listen on a port. onSuccess is called, however the server does not seem to actually be starting. I am wondering if the path of the server.js file is wrong, however I do not know what the structure of the Tizen TV file system is. Has anyone successfully started a node server on a Tizen TV? Any help at all would be much appreciated.
