Hi all,
We're noticing a strange behaviour during RPT call performed by our
adapter. More specifically, we're getting a 500 HTTP Error with the
following description: "Unexpected error while evaluating permissions:
java.lang.RuntimeException: Error while reading attributes" and with a
NullPointerException.
I had a keycloak access token with 5 hours of expiration time and "SSO
Session Idle time", in Keycloak, was set to 30 minutes. I know, it's a
strange configuration, but we've used it just for testing purposes of the
RPT / Authorization part.
Once i've received the error, i've started thinking that the problem was
probably due to the fact that the user's session was expired (i've notice
the error after lunch where i've left the pc alone for about 1 hour), so
i've tried to reproduce the error in this way:
- Login via Resource Owner Password grant flow (via Postman)
- Getting the token and calling our test microservice where the adapter was
configured
- RPT Call worked
- After that, logout the user's session from the user admin console
- Retried the call to the microservice with the same token
- Received the 500 HTTP Error
We're using Keycloak 6.0.1.
I've a question about: is it right that error? In my opinion we should
receive a 401, not 500...
At the bottom you can find the stacktrace.
Thank you very much,
Matteo
