Remote Procedure Call (RPC) not updating position at all

Using new commit in GitLab,
while running the whole simulation,

RPC does not update the car(?)'s position at all.
(This was also the case in the previous implementation where we were using SmartFoxServer).\

While I might be missing something along the lines, I thought it is best to record this as an issue.

In the attachment one can found the logs from RMIServer(top-left), RPC (bottom-left), and restful (right column).

Also, here is the final install result of restful (it fails):
