the query return other entity data patientid , doctorid undefined while patient , doctor 'proto._setctor.instanceproto'

query server return patientid: "a0bb54a2-c347-424c-bbf3-7c05e0286b43",  doctorid: "a0bb54a2-c347-424c-bbf3-7c05e0286b43",   lookupallergyid: 1 // return ok  query client return id: (...) doctor: proto._setctor.instanceproto doctorid: undefined // return undefined lookupallergy: (...) lookupallergyid: 1 modifiedby: (...) modifiedbyid: (...) modifiedon: (...) note: (...) patient: proto._setctor.instanceproto patientid: undefined // return undefined type: (...) 

please, need on how resolve because navigation query returning null example {{vm.allergy.patient.email}} not possible.

thanks.
