Hi Asha and Prakhyat (you will not receive help faster by double-posting), First checks that it is a valid message with idExtractor.isDefinedAt(msg). That will not invoke your prints in idExtractor. Then it uses the shardExtractor, which you see in the logs. Before creating the entry, or delegating to the right node, it must get information from the coordinator. It is probably this that is not successful.
You will find more information about what is going on by enabling akka.loglevel=DEBUG and look log messages from the "/user/sharding" actors.
