ReportService

In a script task in an interpretive business process you need to get "user connection"  with the following syntax:

var userConnection = Get<UserConnection>("UserConnection");

Additionally, please note that if you want to work with process parameters in a script task, you need to write in the following manner:

var parameter1 = Get<Guid>("Parameter1");

Set("Parameter2", parameter1.ToString());

var parameter2 = Get<string>("Parameter2");



Also, from exception message it seems that desired template not exists in the system, so you should check it.

I have a similar requirement to send report automatically to users at a certain frequency. We use Creatio 7.18.5 and the report was built using the old ReportDesigner for 7.14 and was carried over to the new version when we upgraded. 

I tried to follow this article to create the report as part of our process - https://community.creatio.com/articles/generate-printable-and-send-it-attachment-email

When the process is manually run by the user, the report gets generated. But when scheduled to run by Supervisor using timer, it gives below error - 

Terrasoft.Core.InstanceActivationException: Error creating an instance of the "Terrasoft.Tools.DevExpressReport.IReportProvider" class ---> Ninject.ActivationException: Error activating UserConnection using binding from UserConnection to method
Provider returned null.
Activation path:
  3) Injection of dependency UserConnection into parameter userConnection of constructor of type DevExpressConfReportLocalizationReader
  2) Injection of dependency IDevExpressReportLocalizationReader into parameter reportLocalizationReader of constructor of type ConfigurationDevExpressReportProvider
  1) Request for IReportProvider
 
Suggestions:
  1) Ensure that the provider handles creation requests properly.

Below is the report generation part of the code -  

//ReportService reportService = new ReportService(userConnection);
//ReportData report = reportService.GenerateDevExpressReport(entitySchemaUId,reportSchemaUId,null,reportParamaters);
 
DevExpressReportGenerator reportGenerator = new DevExpressReportGenerator();
var configuration = new ReportGeneratorConfiguration {
				ReportTemplateId = !string.IsNullOrEmpty(reportSchemaUId) ? new Guid(reportSchemaUId) : Guid.Empty,
				EntitySchemaUId = !string.IsNullOrEmpty(entitySchemaUId) ? new Guid(entitySchemaUId) : Guid.Empty,
				RecordId = !string.IsNullOrEmpty(recordId) ? new Guid(recordId) : Guid.Empty,
				ReportParameters = !string.IsNullOrEmpty(reportParameters)
					? JsonConvert.DeserializeObject<Dictionary<string, object>>(reportParameters)
					: null
			};
ReportData report = reportGenerator.Generate(userConnection, configuration);

I understand it's an old version of the report but I would appreciate if anyone can provide any insights on what I'm missing.

Hello Nirupama, Can you check if the run elements in the background is disabled ? If that is enabled, then the process will not get the User Connection.
