Hi, Sakit.
What kind of error, at what moment (start up, some flow you tried etc)? Please provide more details. I've tried latest 3.0.2 oxauth/oxtrust modules in my Gluu CE 3.0.2 package (I got it from devel repo ) and at least there was no issues during start up and several OIDC flows I tried. If you still using 3.0.1, do you think it's possible for you to switch to 3.0.2? It will be released soon (and you can get pre-release package right now if you wish so)
