DreamHouse Realty has an approval process.

A common cause of errors in an Approval Process is a breakdown in the " Approver " chain. If an approval step is configured to route to a specific user or a manager who has been deactivated, Salesforce will throw an error when the current step tries to advance. The Platform Administrator should check the " Next Approver " field on the record or the step definition in Setup to ensure the target user is active and has a valid Salesforce license. While field visibility (Options B and C) is important for the user experience, missing field access typically doesn ' t " error out " the approval engine itself; it just prevents the user from seeing the data. Checking for inactive users is the first step in troubleshooting runtime errors in automated routing processes.
