Trouble triggering an Incisor app event with more than one argument

I’m having trouble triggering an Incisor app event with more than one argument.

The console output:

spinResult Defined

spinResult Callback Added

5

undefined (I expect this to read “7777”)

TestAppEvent: CODE VALIDATION FAILED: ‘string=’ expects the parameter ‘string’ to be type ‘string’, but type ‘undefined’ was provided.

How do I get multiple arguments to be available in my callback function?

class ProjectMain
{
    init()
    {
        this.text = new TextAssembly();
        this.text.string = "Build It Once.";

    // Define the event here
        nc.defineAppEvent("spinResult");
        console.log("spinResult Defined");

    // Add the callback for the "spinResult" event
        nc.appEvents.spinResult.addCallback(this, "spinResultCallback");
        console.log("spinResult Callback Added");

    // Trigger the event with multiple arguments
        nc.appEvents.spinResult.trigger(5, "7777");
    }


    /**
    * spinResultCallback
    */
    spinResultCallback(resultData, message)
    {
        console.log(resultData);
        console.log(message);// this should read "7777"
        
        this.text.string = message;

    }
}
