How Can I Get Better Errors From A Flow API

Comments

  • 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.

You can then check for an error in that output from the API call in the external code.[/font]
