I'm trying to create a new subject using oc web services. But, my study configuration doesn't require date of birth and gender. When I tried to manually create a new study subject from openclinica website, it also asked me Study Event and it is a required value. When I tried to use web services, I got the error "Element must not be null" which is not very useful. I followed this example to use web service: https://docs.openclinica.com/3.1/technical-documents/openclinica-web-services-guide/studysubject-web-service
, but it doesn't show how to add a study event from openclinica web service. I tried to use a studyeventOID element, but I'm still getting the same error. How can I know what element am I missing or which elements are required to create a new subject?
Merry Christmas and Happy New Year.
