How Can I Get Better Errors From A Flow API

    Do you have a recommended way for your clients who use the API when it comes to handling (deserializingparsing) the Fault exceptions thrown?

    Examples

    [i]System.ServiceModel.FaultException1[DecisionsFramework.ServiceLayer.Utilities.FrameworkFault]: Object reference not set to an instance of an object. (Fault Detail is equal to DecisionsFramework.ServiceLayer.Utilities.FrameworkFault).[/i] [i] [/i] [i]System.ServiceModel.FaultException1[DecisionsFramework.ServiceLayer.Utilities.FrameworkFault]: [SecurityException] Username/Password is invalid. (Fault Detail is equal to DecisionsFramework.ServiceLayer.Utilities.FrameworkFault).[/i]
    [i] [/i]
    [i]System.ServiceModel.FaultException`1[DecisionsFramework.ServiceLayer.Utilities.FrameworkFault]: Exception of type DecisionsFramework.ServiceLayer.InvalidUserSessionException was thrown. (Fault Detail is equal to DecisionsFramework.ServiceLayer.Utilities.FrameworkFault).[/i]
    [i]
    [/i]
    [i]
    [/i]
    These error messages dont tell us much on their own, and the full error message data only shows up in the Decisions UI.

    [font=Roboto, Arial, Helvetica, sans-serif]You can use a Catch Exception step in the flow youre calling, place a Create Data step after it, and generate a JSON-formatted error message to pass into the flows output. You can then check for an error in that output from the API call in the external code.[/font]
