Wrapper had an addition line of error at the top - ```auto INFO | jvm 2 | 2019/10/04 10:41:16 | E [t.e.a.history] [14:41:16]: Error storing tag history data store-forward-name=DB INFO | jvm 2 | 2019/10/04 10:41:16 | java.lang.IllegalArgumentException: Specified historical sink 'DB' does not exist.

I clicked edit configuration, I saw my datase stuff, clicked save, and then it appeared normally. However, in my logs, I then saw this new error after the gateway implemented the changes and it looks like it may be related ```auto java.lang.AbstractMethodError: Receiver class com.mysql.jdbc.Connection does not define or inherit an implementation of the resolved method abstract getSchema()Ljava/lang/String; of interface java.sql.Connection. at org.apache.commons.dbcp2.DelegatingConnection.getSchema(DelegatingConnection.java:941) at org.apache.commons.dbcp2.DelegatingConnection.getSchema(DelegatingConnection.java:941) at com.inductiveautomation.ignition.gateway.datasource.SRConnectionWrapper.getSchema(SRConnectionWrapper.java:546) at com.inductiveautomation.ignition.gateway.db.schema.DBTableSchema.refreshTableState(DBTableSchema.java:187) at com.inductiveautomation.ignition.gateway.db.schema.DBTableSchema.verifyAndUpdate(DBTableSchema.java:87) at com.inductiveautomation.gateway.tags.history.storage.TagHistoryDatasourceSink.checkTables(TagHistoryDatasourceSink.java:1110) at com.inductiveautomation.gateway.tags.history.storage.TagHistoryDatasourceSink.initialize(TagHistoryDatasourceSink.java:237) at com.inductiveautomation.ignition.gateway.history.sf.sinks.AbstractSink.tryToInit(AbstractSink.java:94) at com.inductiveautomation.gateway.tags.history.storage.TagHistoryDatasourceSink.tryToInit(TagHistoryDatasourceSink.java:218) at com.inductiveautomation.ignition.gateway.history.sf.sinks.AbstractSink.startup(AbstractSink.java:43) at com.inductiveautomation.gateway.tags.history.storage.TagHistoryDatasourceSink.startup(TagHistoryDatasourceSink.java:228) at com.inductiveautomation.ignition.gateway.history.sf.sinks.AggregateSink.startup(AggregateSink.java:131) at com.inductiveautomation.ignition.gateway.history.DefaultStoreAndForwardEngine.startup(DefaultStoreAndForwardEngine.java:187) at com.inductiveautomation.ignition.gateway.history.StandardStoreAndForwardEngine.updateSettings(StandardStoreAndForwardEngine.java:91) at com.inductiveautomation.ignition.gateway.history.HistoryManagerImpl.ensureStoreAndForwardEngineLoaded(HistoryManagerImpl.java:444) at com.inductiveautomation.ignition.gateway.history.HistoryManagerImpl$1.recordUpdated(HistoryManagerImpl.java:97) at com.inductiveautomation.ignition.gateway.history.HistoryManagerImpl$1.recordUpdated(HistoryManagerImpl.java:83) at com.inductiveautomation.ignition.gateway.localdb.PersistenceInterfaceImpl.notifyRecordUpdated(PersistenceInterfaceImpl.java:178) at com.inductiveautomation.ignition.gateway.redundancy.RedundantPersistenceInterfaceImpl.doNotifyRecordUpdated(RedundantPersistenceInterfaceImpl.java:88) at com.inductiveautomation.ignition.gateway.redundancy.RedundantPersistenceInterfaceImpl$RecordUpdateListener.recordUpdated(RedundantPersistenceInterfaceImpl.java:295) at com.inductiveautomation.ignition.gateway.redundancy.RedundantPersistenceInterfaceImpl$RecordUpdateMessage.notify(RedundantPersistenceInterfaceImpl.java:346) at com.inductiveautomation.ignition.gateway.redundancy.RedundantPersistenceInterfaceImpl$RecordUpdateListener.receiveCall(RedundantPersistenceInterfaceImpl.java:278) at com.inductiveautomation.ignition.gateway.redundancy.QueueableMessageReceiver.receiveCall(QueueableMessageReceiver.java:47) at com.inductiveautomation.ignition.gateway.redundancy.RedundancyManagerImpl.dispatchMessage(RedundancyManagerImpl.java:813) at com.inductiveautomation.ignition.gateway.redundancy.RedundancyManagerImpl$ExecuteTask.run(RedundancyManagerImpl.java:849) at com.inductiveautomation.ignition.common.execution.impl.BasicExecutionEngine$ThrowableCatchingRunnable.run(BasicExecutionEngine.java:518) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.run(Unknown Source) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source) ``` --- _[View the full topic](https://forum.inductiveautomation.com/t/specified-historical-sink-db-does-not-exist/28824)._
