@yashdsaraf I’m getting following error in your latest master and merged code with my branch when viewing the patients. Do you have any idea?

There was an unexpected error (type=Internal Server Error, status=500).

JSON encoding error: org.hl7.fhir.dstu3.model.Encounter$EncounterStatus cannot be cast to org.hl7.fhir.dstu3.model.Enumerations$AdministrativeGender; nested exception is com.fasterxml.jackson.databind.JsonMappingException: org.hl7.fhir.dstu3.model.Encounter$EncounterStatus cannot be cast to org.hl7.fhir.dstu3.model.Enumerations$AdministrativeGender (through reference chain: java.util.ArrayList[0]-\>org.openmrs.model.CPatient[“gender”])
