Hey,
I just created a new pull request for my work in progress: I am currently working on new processors that are similar to the existing BooleanTimer and BooleanCounter in streampipes.processors.transformation.jvm.processor, but support string values. However, I am running into the following bug, when adding the StringTimerController to the TransformationJvmInit file and can't make sense of it. 15:44:43.523 SP [XNIO-1 task-26] ERROR io.undertow.request - UT005023: Exception handling request to / javax.servlet.ServletException: java.lang.NullPointerException: inStream parameter is null at org.glassfish.jersey.servlet.WebComponent.serviceImpl(WebComponent.java:408) at org.glassfish.jersey.servlet.WebComponent.service(WebComponent.java:346) It should work as the codebase is simply borrowed from the existing _BooleanTimer_. I double-checked names, id's, etc. but I am afraid I am unable to identify the root cause. Any help is appreciated! Kind regards, Felix
