The issue is reproducible only if upgrade is available for the instance. For instances on the latest version of the application, error does not appear and screen is opened without any error.


Software-related issue #OA-14619.


Contact your Technical Account Manager to clarify current status of the issue.

As a workaround, upgrade the application instance using pem.APS.upgradeApplicationInstance API request.
