No default persistence


This question has been asked before, but the solution offered there did not work for me.

I am trying to get historical data to compute change

val weatherChange = Weather_Temperature.historicState(now.minusMinutes(2)) as DecimalType

But I am getting the following warning, and as a result the variable remains ‘null’.

19:03:00.022 [WARN ] [nce.extensions.PersistenceExtensions] - There is no default persistence service configured!
19:03:00.025 [WARN ] [nce.extensions.PersistenceExtensions] - There is no queryable persistence service registered with the id 'null'`

Default persistence is set to rrd4j in runtime.cfg (org.eclipse.smarthome.persistence:default=rrd4j), also there is data in rrd4j files as the graphs that use the same data display it correctly.

Many thanks,

managed to solve the problem by updating to the latest snapshot.
