Failed to send notification. The parameter login cannot be empty or bigger than 251 characters.
Failed to send notification. The parameter login cannot be empty or bigger than 251 characters.
Resolution
Check to see if the email is sent to {Common:Manager} or other profile-focused reference:
- Add a "Log to History" action to the Workflow as the first action.
- Choose to log the "Manager" (or similar) reference.
- Run the Workflow and then check the Workflow History to confirm the value being picked up.
Error Code
Failed to send notification. The parameter login cannot be empty or bigger than 251 characters.
Additional Information
This is caused by an incorrect reference, usually being populated by a query to a user profile. For example a {Common:Manager} reference in an email, constant or other variable which is returning a null value.
In some non-production environments, the Manager field (as an example) in Active Directory is not populated.
