Viewing the Job Details pages now requires a new permission getJobDetails (defined within WorkflowEngine) that may not be enabled in some customers' custom roles.
If you have custom roles and want those roles to access the Job Details page, then ensure they have access to either the WorkFlowEngine apiread role or the getJobDetails method.
Hint: To do this, find the custom role in Authorization, search for getJobDetails in the WorkFlowEngine application, and add it to the role.
