Hi All,
I have used plugin for stage movement based on field change but getting error "Index out of range & must be non negative & less than d size of collection."
I have written the below code for stage movement to next stage based on field value here an option set field Action if it is Approved then it should go to next stage.Sometimes its moving for existing record,But getting error now Index out of range errormust be non negative & less than the size of the collection.Parameter name : Index.
public void Execute(IServiceProvider serviceProvider)
{
//get the execution context
IPluginExecutionContext executionContext = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
//get the organization service factory that creates the organization service
IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
organizationService = serviceFactory.CreateOrganizationService(executionContext.UserId);
//Create the organization service context that gives the ability of querying
organizationServiceContext = new OrganizationServiceContext(organizationService);
Entity incident = null;
if (executionContext.InputParameters.Contains("Target") && (executionContext.InputParameters["Target"] is Entity))

Any idea or help...
