JavaException when calling Instant App from a bot

Content

I've created a simple Bot using OMCe bots only stack. Now I want to integrate a simple Instant App into my bot flow.

 

I used one of the Instant App's templates offered by the platform: I created one using the wizard and then I activated it. I created this state to call the Instant App:

 

interactiveState:

    component: "System.Interactive"

    properties:

      sourceVariableList: "name, lastname"

      variable: "outputMessage"

      id: "Test_Instant_App"

      prompt: "test phrase"

    transitions: {}

 

When the bot reach this particular state I get the following error:

 

"errorMessage": "javaException:Schema specific part is opaque."
