4:25 a.m.
Hello,
I'm experiencing a strange error while trying to retrieve a token. Although
initially the application may function properly and tokens issued normally,
something happens when i use the Admin REST api that triggers the error.
After that no tokens can be issued and an NPE appears in the log. Usually
this happens after trying to drop some clients.
Btw, i'm using keycloak-1.4.0.Final.
Here is the command i use to get the token:
curl -k -X POST
https://identity.restcomm.com/auth/realms/restcomm/protocol/openid-connec...
-d "grant_type=password" -d "client_id=restcomm-identity-rest" -d
"username=otsakir" -d "password=...."
And here is what i get in the logs:
09:12:36,414 ERROR [io.undertow.request] (default task-4) UT005023:
