Abbyy OCR Create Batch Error using Abbyy.UiPath.FlexiCapture.MultiTaskActivities.


I am trying to work with Abbyy 12 from UiPath 2019.4. But I am getting this error while creating a Batch in the project. Could you please let me now what could be the issue

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.InvalidOperationException: Failed to add a new batch. ----> System.ServiceModel.CommunicationException: There was an error while trying to serialize parameter urn: The InnerException message was ‘Member Value in type Abbyy.FlexiCapture.AppSrvApi.RegistrationProperty cannot be serialized. This exception is usually caused by trying to use a null value where a null value is not allowed. The ‘Value’ member is set to its default value (usually null or zero). The member’s EmitDefault setting is ‘false’, indicating that the member should not be serialized. However, the member’s IsRequired setting is ‘true’, indicating that it must be serialized. This conflict cannot be resolved. Consider setting ‘Value’ to a non-default value. Alternatively, you can change the EmitDefaultValue property on the DataMemberAttribute attribute to true, or changing the IsRequired property to false.’


Hi All,

With the same Abbyy project scope, able to get the batch stage using “Get Batch Stage” activity. But not working for “Create Batch” activity

Finally got solution, when I remove the “batchregistrationparameters” property value from the “Create Batch” activity, I am able to create batch from UiPath in Abbyy Flexicapture Project setup station.
