[GitHub] [streampipes] dominikriemer opened a new issue, #573: Pipeline with MQTT sink does not start

[GitBox <gi...@apache.org>]

dominikriemer opened a new issue, #573:
URL: https://github.com/apache/streampipes/issues/573

   I created a pipeline with the 'Machine Data Simulator' as a source and MQTT publisher as a sink.
   
   When storing the pipeline the UI shows the following error: "Your pipeline could not be stored."
   
   It seems to be a problem with the secret static property. I also tried to set the values for the basic auth, but the error was the same. 
   
   In the backend this exception occurs:
   
   backend_1 | 09:58:30.390 SP [http-nio-8030-exec-1] ERROR o.a.c.c.C.[.[.[.[.a.s.b.StreamPipesResourceConfig] - Servlet.service() for servlet [org.apache.streampipes.backend.StreamPipesResourceConfig] in context with path [/streampipes-backend] threw exception [java.lang.NullPointerException] with root cause
