Configuring an Application in the Streaming Application Manager in HDF-3:

When I dragged a KAFKA source tile component unto the Application Builder canvas - and double clicked on it to configure/specify the mandatory argument 'KAFKA TOPIC*'; on selecting the correct topic from the dropdown list - the error 'SCHEMA NOT FOUND' was displayed by the application builder service.

I have attached a screenshot of the error encountered below.screen-shot-2017-07-18-at-12057-pm.png

Similar Error here. SAM and Schema Registry seem to not work together correctly. Are there known work-arounds?
