Hello, As I am trying to extend what we have to other sources, I changed some code. Looks like deserialization is broken.
Here is a sample stream input: {"creation_time":"2015-02-19T04:03:51Z","alert_policy_name":"Alert Policy","application_name":"PROD AWS","business_unit_l1":"CEG"} envelope.getMessage().toString() Transforms it to: {creation_time=2015-02-04T20:41:36Z, alert_policy_name=Alert Policy,application_name=Prod AWS,business_unit_l1=CEG} As we can see, the json structure seem to be broken. I have this in the config file: systems.kafka.streams.Alert.samza.msg.serde=json systems.kafka.samza.msg.serde=json Wondering what could be wrong. - Shekar
