It looks like you have an error message in your Guided Navigation response.
If you check the dgraph logs on your MDEX server, you should be able to get the full detail regarding what went wrong with your query to the engine. From the information below, you should be looking on the WID0609 machine at the logs\dgraphs\[DGRAPHID]\[DGRAPHID].log file underneath your application's working directory.
One other question I forgot to ask, is your dgraph running on port 18000? The error you're getting is a 404 which could also mean you're trying to hit a dgraph that's not active (or running on a different port).
Ensure that the cartridges copied from the reference application do not contain any old references to ref app Discover properties, this can cause an error to be thrown. Amend the cartridges for your own props, sort props, rel ranks etc
