Data Hub Suddenly Stopped Working

0
Hello. We are suddenly experiencing an issue with Data Hub retrieves and are getting the following error:Could not find attribute '_ID' in column map for entity We have made no changes to these retrieves and no changes to the source application. It just started happening. Both of the affected consuming  apps are on 9.9.1. The source is on 8.18.15. I have tried cleaning the deployment package and redeploying. This sometimes works, but only temporarily. Any ideas as to what could be happening here.   9:31:57 AMAPPINFOInternalXPathTextGetRequest (depth = 0, amount = 1): //OperationalDQM.Locations[StatusIndicator = 'A'] [FacilityType = 'LDYP'] 9:31:57 AMAPPINFOat OperationalDQM.ACT_CreateSortString (RetrieveByXPath : 'Retrieve Locations from database') 9:31:57 AMAPPINFOAdvanced stacktrace: 9:31:57 AMAPPINFOat com.mendix.modules.microflowengine.MicroflowUtil.processException(MicroflowUtil.java:83) 9:31:57 AMAPPINFOCaused by: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.connectionbus.ConnectionBusRuntimeException: An exception has occurred for the following request(s): 9:31:57 AMAPPINFOInternalXPathTextGetRequest (depth = 0, amount = 1): //OperationalDQM.Locations[StatusIndicator = 'A'] [FacilityType = 'LDYP'] 9:31:57 AMAPPINFOat com.mendix.basis.actionmanagement.ActionManager.executeSync(ActionManager.scala:84) 9:31:57 AMAPPINFOCaused by: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.connectionbus.ConnectionBusRuntimeException: An exception has occurred for the following request(s): 9:31:57 AMAPPINFOInternalXPathTextGetRequest (depth = 0, amount = 1): //OperationalDQM.Locations[StatusIndicator = 'A'] [FacilityType = 'LDYP'] 9:31:57 AMAPPINFOat com.mendix.util.classloading.Runner$.withContextClassLoader(Runner.scala:23) 9:31:57 AMAPPINFOCaused by: com.mendix.connectionbus.ConnectionBusRuntimeException: An exception has occurred for the following request(s): 9:31:57 AMAPPINFOInternalXPathTextGetRequest (depth = 0, amount = 1): //OperationalDQM.Locations[StatusIndicator = 'A'] [FacilityType = 'LDYP'] 9:31:57 AMAPPINFOat com.mendix.connectionbus.RequestAnalyzer.doRequest(RequestAnalyzer.scala:35) 9:31:57 AMAPPINFOCaused by: com.mendix.connectionbus.ConnectionBusRuntimeException: Could not find attribute '_ID' in column map for entity 'OperationalDQM.Locations', map = com.mendix.connectionbus.mapping.HashBiMap@11581dad 9:31:57 AMAPPINFOat com.mendix.connectionbus.mapping.MapperBase.getColumnName(MapperBase.scala:115) 9:31:57 AMAPPINFOat com.mendix.connectionbus.handler.RemoteKeyMappingImpl$Retriever.$anonfun$getTableInfo$1(RemoteKeyMappingImpl.scala:256)
