Hi  
i am running Packet-beat in my server.  
in index mapping i set disabled dynamic. it mean if new data coming . don't create new fields.  
in my mapping there is not extra field but when i send a request from postman . there is a new field in my result but i'm sure its not in my mapping.  
how is possible?
