Error in documentation - TEI JSON syntax

Hi Devs,
I am trying to generate a json output file for transferring data via the api to a dhis instance. I have tried using the guide on found that the syntax for “Create and enroll tracked entity instances” is wrong i.e. it reads dateOfEnrollment and dateOfIncident. These should read enrollmentDate and incidentDate for the attached json snippet to work. Also IS it possible to do multiple TEI’s and enrollments in the same payload and how would the syntax look like, since the attached snippet is for one TEI.
