Possible bug prevents data to be stored after restarting opc ua server

[leonmeerfeld]

I collect about 50 values from a upc ua server. the upc ua server is connected to a wincc instance. which got restarted. After the restart ca. 20 out of the 50 stopped being inserted into the datalake. on the datalake in the pipeline I get the following error log:
java.lang.IllegalArgumentException: Expecting a positive number for fields size at org.influxdb.impl.Preconditions.checkPositiveNumber(Preconditions.java:35) at org.influxdb.dto.Point$Builder.build(Point.java:387) at org.apache.streampipes.dataexplorer.commons.influx.InfluxStore.onEvent(InfluxStore.java:79) at org.apache.streampipes.dataexplorer.commons.TimeSeriesStore.onEvent(TimeSeriesStore.java:64) at org.apache.streampipes.sinks.internal.jvm.datalake.DataLakeSink.onEvent(DataLakeSink.java:109) at org.apache.streampipes.wrapper.standalone.runtime.StandaloneEventSinkRuntime.process(StandaloneEventSinkRuntime.java:55) at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector.send(StandaloneSpInputCollector.java:56) at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector.lambda$onEvent$0(StandaloneSpInputCollector.java:51) at java.base/java.util.concurrent.ConcurrentHashMap.forEach(Unknown Source) at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector.onEvent(StandaloneSpInputCollector.java:51) at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector.onEvent(StandaloneSpInputCollector.java:30) at org.apache.streampipes.messaging.kafka.SpKafkaConsumer.lambda$run$0(SpKafkaConsumer.java:105) at java.base/java.lang.Iterable.forEach(Unknown Source) at org.apache.streampipes.messaging.kafka.SpKafkaConsumer.run(SpKafkaConsumer.java:105) at java.base/java.lang.Thread.run(Unknown Source)
Does anyone know whats going on here?
We'll test some more cases with restarts and reconnecting and I'll update here.
