This is related to my observation here: https://issues.apache.org/jira/browse/STREAMPIPES-299 

It seems the StaticPropertyAlternative does respect the default set value even though correctly rendered in the UI. I found a quick-test to see if its working is to actively select another option then go back to the default one. This worked for me at least. This lead me to the assumption that it's a UI back rather that a backend/PE issue.

> 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:
