Philipp Zehnder created STREAMPIPES-390:
-------------------------------------------
Summary: Pipeline with MQTT sink does not start
Key: STREAMPIPES-390
URL: https://issues.apache.org/jira/browse/STREAMPIPES-390
Project: StreamPipes
Issue Type: Bug
Components: Pipeline Elements
Reporter: Philipp Zehnder
Fix For: 0.68.0
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:
