I have configured Infinispan Cluster version 14.0 with Keycloak version 21.0.2-debian-11-r0 on EKS Cluster. When I bring up Keycloak, I am seeing below error:
org.infinispan.commons.dataconversion.EncodingException: ISPN000492: Cannot find transcoder between 'application/x-protostream' to 'application/x-jboss-marshalling'
What can be the issue? Why am I getting Encoding error using same encoding at both side?
I have used application/x-jboss-marshalling encoding in infinispan server and keycloak cache configs.
My remote-server configuration looks like
<distributed-cache name="loginFailures" owners="2">
<expiration lifespan="900000000000000000"/>
<remote-store cache="loginFailures" xmlns="urn:infinispan:config:store:remote:13.0"
purge="false"
preload="false"
shared="true" segmented="false"
connect-timeout="${env.KEYCLOAK_REMOTE_ISPN_CONN_TIMEOUT:2000}">
<remote-server host="${env.INFINISPAN_SERVER}" port="${infinispan.bind.port:11222}"/>
<security>
<authentication>
<digest username="${env.KEYCLOAK_REMOTE_ISPN_USERNAME:keycloak}"
password="${env.KEYCLOAK_REMOTE_ISPN_PASSWORD:password}"
realm="default"/>
</authentication>
</security>
<property name="rawValues">true</property>
<property name="marshaller">org.keycloak.cluster.infinispan.KeycloakHotRodMarshallerFactory</property>
</remote-store>
</distributed-cache>
Found fix for this. Ref: https://github.com/keycloak/keycloak/issues/20031
Now Keycloak version 21 is working with Infinispan cache.
