WEB API Error in DHIS2.30

Hi dear adebusoye

I am using dhis2 version 2.30, compiled from github (last version),
When i try to create trackedEntity with weeb api, i get the following error
It seem’s TrackedEntity has been removed from TrackedEntityInstance class
how can i fix the problem?

ERROR:
{“httpStatus”:“Internal Server Error”,“httpStatusCode”:500,“status”:“ERROR”,“message”:“Unrecognized field “trackedEntity” (class org.hisp.dhis.dxf2.events.trackedentity.TrackedEntityInstance), not marked as ignorable (14 known properties: “trackedEntityInstance”, “lastUpdatedAtClient”, “lastUpdated”, “createdAtClient”, “trackedEntityType”, “orgUnit”, “inactive”, “enrollments”, “featureType”, “attributes”, “deleted”, “relationships”, “created”, “coordinates”])\n at [Source: {“trackedEntityInstance”: “IKjF4BZg3hb”,“trackedEntity”: “nEenWmSyUEp”,“orgUnit”: “iq6Pt6QzM4d”,“trackedEntityType”: “MCPQUTHX1Ze”,“attributes”:[{“attribute”:“spFvx9FndA4”,“value”:“53”},{“attribute”:“w75KJ2mc4zz”,“value”:”???"},{“attribute”:“hqtiQfZ66yc”,“value”:"???"},{“attribute”:“zDhUuAYrxNC”,“value”:"???"},{“attribute”:“AuPLng5hLbE”,“value”:“51961113”},{“attribute”:“EO4ms2Ju3nf”,“value”:“1”},{“attribute”:“gHGyrwKPzej”,“value”:“2013-09-17”},{“attribute”:“P2cwLGskgxn”,“value”:“123”},{“attribute”:“Agywv2JGwuq”,“value”:""}],“enrollments”:[{“orgUnit”: “iq6Pt6QzM4d”,“program”: “LaWt5AR1tfl”,“enrollmentDate”: “2013-09-17”,“incidentDate”: “2013-09-17”}]}; line: 1, column: 59] (through reference chain: org.hisp.dhis.dxf2.events.trackedentity.TrackedEntityInstance[“trackedEntity”])"}
