No Reviewer Assigned Error Message in Okta Access Certifications Preview Reviewer

When creating a Certification Review Campaign, on the Reviewer step, when the First-level reviewer is set as Manager, and when using the preview function in Access Certifications, the following error message is received:

No reviewer assigned. The fallback reviewer will be used as a reviewer for (Username). 

• Access Certifications 
• Okta Identity Governance

The user selected for the preview does not have a manager's login (or Okta User ID) in the managerId attribute for the user's profile.

To resolve this, there are a couple of options:

1. In the User's Profile, set the managerId value to the manager's username (login). 
2. If in the User's Profile, the manager's username (login) is referenced in another attribute, also use Okta Expression Language to evaluate properly. 
   1. Change the Reviewer to Custom.
   2. Then, enter the desired Okta Expression Language.
      • For example, if the manager's login is stored in the manager attribute, also use user.profiler.manager.

• • • For more Okta Expression Language samples for Certifications, see the Sample expressions section.
