How to fix this error 'System.InvalidOperationException: Cannot serialize the DataTable. DataTable name is not set.' in Wait for document Validation and Resume(Action Center)

Hi @Pravin_Mandadi ,

Could you make sure if you have followed the Best Practices mentioned in the document for Orchestration Process (Create Validation/Wait For Resume activities process) :
https://docs.uipath.com/studio/standalone/2023.4/user-guide/orchestration-process#best-practices

Do check for any other type of variables used in the Main workflow (Also the Enclosing Sequences where the Wait for Resume activity is used) and change its scope.
