Please tell me how to set a Date type field to blank in ‘UiPath.Salesforce.Activities.UpdateRecord’. Even if you set a variable with ‘Nothing’ to the Value, it will not update to blank. If you try using “” as a String, it will result in an error.
Just try to set that value to blank in salesforce manually and try to get the value and check what you are getting…depensing on that we can set the value
