Hello, everyone, My partners (Michele and Federico, in cc) and I are trying to use an InfluxDB for one of our projects. Since we ran into an issue while trying to set everything up, we decided to try and create the test case that was presented here<https://cwiki.apache.org/confluence/display/STREAMPIPES/Description+for+E2E+Tests>, under InfluxDB section.
We have configured the InfluxDB data sink according to the instructions. However, when we start the pipeline, we get the following error: pipeline-elements-all-jvm_1 | Exception in thread "Thread-7" java.lang.IllegalArgumentException: Key not found pipeline-elements-all-jvm_1 | at org.apache.streampipes.model.runtime.Event.lambda$getNestedItem$2(Event.java:97) pipeline-elements-all-jvm_1 | at org.apache.streampipes.model.runtime.Event$$Lambda$885/0x00000000541938f0.get(Unknown Source) pipeline-elements-all-jvm_1 | at java.util.Optional.orElseThrow(Optional.java:290) pipeline-elements-all-jvm_1 | at org.apache.streampipes.model.runtime.Event.getNestedItem(Event.java:97) pipeline-elements-all-jvm_1 | at org.apache.streampipes.model.runtime.Event.getFieldBySelector(Event.java:90) pipeline-elements-all-jvm_1 | at org.apache.streampipes.model.runtime.Event.getFieldBySelector(Event.java:82) pipeline-elements-all-jvm_1 | at org.apache.streampipes.sinks.databases.jvm.influxdb.InfluxDbClient.save(InfluxDbClient.java:166) pipeline-elements-all-jvm_1 | at org.apache.streampipes.sinks.databases.jvm.influxdb.InfluxDb.onEvent(InfluxDb.java:54) pipeline-elements-all-jvm_1 | at org.apache.streampipes.wrapper.standalone.runtime.StandaloneEventSinkRuntime.process(StandaloneEventSinkRuntime.java:50) pipeline-elements-all-jvm_1 | at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector.send(StandaloneSpInputCollector.java:54) pipeline-elements-all-jvm_1 | at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector.lambda$onEvent$0(StandaloneSpInputCollector.java:48) pipeline-elements-all-jvm_1 | at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector$$Lambda$881/0x0000000054170f00.accept(Unknown Source) pipeline-elements-all-jvm_1 | at java.util.concurrent.ConcurrentHashMap.forEach(ConcurrentHashMap.java:1597) pipeline-elements-all-jvm_1 | at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector.onEvent(StandaloneSpInputCollector.java:48) pipeline-elements-all-jvm_1 | at org.apache.streampipes.wrapper.standalone.routing.StandaloneSpInputCollector.onEvent(StandaloneSpInputCollector.java:29) pipeline-elements-all-jvm_1 | at org.apache.streampipes.messaging.kafka.SpKafkaConsumer.run(SpKafkaConsumer.java:120) pipeline-elements-all-jvm_1 | at java.lang.Thread.run(Thread.java:823) ... and no data gets stored in it. We checked that the data can, in fact, be stored in this DB (we manually stored some data in it) and retrieved with InfluxDB Data Stream. So, we are certain that the DB works properly, and that the issue lies in the InfluxDB data sink. In addition, on an unrelated note, we noticed that upon using the pipeline that has Notification Sink, and when we get some notifications, the notification icon still has the number of notifications displayed in it, even though we actually saw and deleted these notifications. It acts as if they were unread all the time. We believe that this is strange behavior, and we wanted to report that, as well. Let us know if you need anything else. Kindest regards, Branislav
