It looks you deleted some client, but his composite roles were not properly deleted. It might be a bug though, but not sure. It will be cool if you can provide more detailed steps to reproduce. Are you using default H2 DB or some else?

Thanks,

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-connect/token -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: Exception handling request to /auth/realms/restcomm/protocol/openid-connect/token: java.lang.RuntimeException: request path: /auth/realms/restcomm/protocol/openid-connect/token
