custom service/client init Order

Question

hi,
In my device(nr51), have multi service and one client.
when i initial the client first ,then to setup service. this follow is O.K.
But, if i initial the service, and setup client . get a error when sd_ble_gattc_primary_services_discover(Attribute Not Found Error Code) 
 We do(deal with) it in order? 
 service: (sd_ble_uuid_vs_add,sd_ble_gatts_service_add and sd_ble_gatts_characteristic_add) 
 client: (sd_ble_uuid_vs_add,sd_ble_gattc_primary_services_discover,sd_ble_gattc_characteristics_discover and
sd_ble_gattc_descriptors_discover)

hi,
i maybe descriptor error question about this issue.
the service and client is custom uuid ,(service custom uuid,A; client custom uuid,B)
so when i init the client first, the ble use the correct uuid(B) to find .
on the hand, if i first use service init ,then setup client( sd_ble_gattc_primary_services_discover)
to found . it Still use service uuid(A) not client uuid(B) to find, so that will get the Attribute Not Found Error Code.
so i think sd_ble_gattc_primary_services_discover function which is use first add uuid to search.
