If you are upgrading from a previous version of Conga Contracts for Salesforce, you see the following error when you try to True-Up a Managed Clause to a null value:
Something bad happened
Latest Revision Text: Clause text is required.
The latest version of Conga Contracts for Salesforce removed the validation rule.
Navigate to the Salesforce Setup page > Objects. Locate Managed Clause and disable the Require_Text validation rule.
