Problem with running Tests/eample

Hey, I am trying to run end to end example given in the akka-persistence-cassandra on alma linux but on running “sbt -Dconfig.resource=local.conf -Dakka.cluster.roles.0=write run” I am getting this error: ‘object actor is not a member of package akka’. how can I run the example?

What sample is it you are trying to run?
