I configured cross-site replication using infinispan 9.0.0.CR3 and everything worked then upgraded it to 9.0.0.Final but same configuration failed to perform cross-site replication with the latest version.

During debugging I observed the following error when trying to update cache default from ispn-cli(infinispan-server-9.0.0.Final/ispn-cli.sh

FLYCTL0158: Operation handler failed: java.lang.IllegalArgumentException: newValue is null

I deployed a fresh Infinispan 9.0.0.Final without any customization in standalone mode but still got same error.

With a out of the box 9.0.0.CR3 deployment cache update worked fine
