DreamHouse Realty has an approval process. A manager attempts to approve the record but receives an error. What should the administrator review to troubleshoot this request?

Updating field-level security to 'view' fields would not cause an approval error; errors typically occur from insufficient 'edit' permissions for fields updated by the process, not merely viewing them.

Page layout visibility of fields does not affect the backend execution of an approval process; fields can be updated by the process even if they are not visible on the page layout.

If the user designated as the next approver in an approval step is inactive, or if the field used to determine the next approver is empty, the system will raise an error because it cannot find a valid recipient for the approval request.

Adding a delegated approver is a proactive measure for when a primary approver is unavailable, but it does not resolve the root cause of an inactive or missing primary approver that is causing the initial error.
