    Thingworx Machine Learning: Unable to view bean pro demo data in Discover extension

    Greetings,

     

    I'm using Thingworx Machine Learning VM 50.4. I'm running Thingworx 6.6.0. I've installed the ThingworxNeuron and NeuronDiscover extensions as described here:

    https://share.ptc.com/sites/sales/ic/IoT%20Presales%20Enablement/_layouts/WordViewer.aspx?id=/sites/sales/ic/IoT%20Presa…

     

    I can get the Discover Landing Page mashup loaded. And the top portion is actually pulling data from the bean pro data set, however, there is no data displayed in any tabs and i see several 500 errors in the console. You can find more details on the errors here:

    https://support.ptc.com/apps/case_logger_viewer/auth/ssl/case=12897667

     

    When i view the Thingworx application monitor log files, i see a lot errors like the following:

    [context: com.thingworx.webservices.context.HttpExecutionContext@7c47a98e][message: Execution error in service script [TW.Discover.Helper GetBooleanPVAResults] : Wrapped com.thingworx.common.exceptions.InvalidRequestException: Execution error in service script [TW.Discover.Helper QueryPVAPredictionsResults] : TypeError: Cannot call method "RetrieveMostRecentPredictionsResult" of null (QueryPVAPredictionsResults#2) Cause: Execution error in service script [TW.Discover.Helper QueryPVAPredictionsResults] : TypeError: Cannot call method "RetrieveMostRecentPredictionsResult" of null (QueryPVAPredictionsResults#2)]

     

     

    Has anyone else had any success viewing the bean pro demo data or the parking kiosk demo data in the Discover Landing page mashup?
