Hi,

I've created a Flow that utilises an Apex Plugin that takes the nominated Date from the Flow (CurrentDate), adds 1 month and returns the new date into 'NextDate'. Both fields exist as Date fields on the Flow, however when running the flow it returns the following error:

An unhandled fault has occurred in this flow

An unhandled fault has occurred while processing the flow.

The Apex Code I'm using is pasted below. Any help on why it's not working would be appreciated?



global class MicrosoftLAR implements Process.Plugin {

    global Process.PluginResult invoke(Process.PluginRequest request)    {

        Date CurrentDate = (Date)request.inputParameters.get('CurrentDate');

        Date TempDate = Date.newInstance(CurrentDate.year(),CurrentDate.month(),CurrentDate.day());

        Date NextDate = TempDate.addMonths(1);

        Map<String, Object> result = new Map<String, Object>();

        result.put('NextDate', NextDate);

        return new Process.PluginResult(result);

    }

    global Process.PluginDescribeResult describe()    {

        Process.PluginDescribeResult result = new Process.PluginDescribeResult();

        result.description='This plug-in adds 1 month to a given date and returns the result.';

        result.tag='Next Schedule Date';

        result.inputParameters = new List<Process.PluginDescribeResult.InputParameter> {

            new Process.PluginDescribeResult.InputParameter('CurrentDate',

            Process.PluginDescribeResult.ParameterType.DATE, true)

        };

        result.outputParameters = new List<Process.PluginDescribeResult.OutputParameter> {

            new Process.PluginDescribeResult.OutputParameter('NextDate',

            Process.PluginDescribeResult.ParameterType.Date)

        };

        return result;

    }

}
