Environment

Ops Manager 3.0.39

Resolution

Under certain circumstances, certain instance jobs may have no parameters configured and Ops Manager does not guard against this situation on older versions.

The solution is to upgrade Ops Manager to 3.0.40+ or higher which contains a fix. Please obtain the latest Ops Manager release from Broadcom Downloads and arrange an upgrade following documentation for Upgrading your Tanzu Operations Manager deployment.
