"Whoops! Error loading Experience (ERROR_UNKNOWN)


"Whoops! Error loading Experience (ERROR_UNKNOWN)

Hello All,


I installed ThingWorx-Platform-Postgres-8-3-0  and  Vuforia Studio Experience Service  es-8-1-3-b503-253-linux-x64  on the same  Ubuntu 18.04 machine using VM.

Experience Service uses 2019 port (regulare http).

Tomcat 8.5.23 starting without any errors.

After starting experience service with "./" command without any options I am getting the following log:


user@user-virtual-machine:/opt/ptc/twx-es/bin$ ./

After publishing simple spatial experience from examples I am getting the following error on vuforia view (Android) screenshot attached.

Any idea, how to solve this issue?



@skolengineer  There seems to be some configuration issue. Request to review the configuration.json which should be inside your ES installation director folder. Make sure parameter domain_id_resolver  is pointing to your ES URL.


Also, you can start the ES in debug mode with below command to get more details in console-

DEBUG=vxs* ./


Hello @dupatel 


Thanks for the reply, let me check the configuration and get back to you.

Hello @skolengineer


Did you resolve the issue?

I have the exact same problem and already set the domain_id_resolver.
