Dashboards needed to create objects in Kubernetes that were not included in the COO API that can be imported, due to latest versions of COO being based on Go 1.21. This has changed and now T-O can import the latest COO dependency, so that kind of direct yaml generation is not needed anymore and can be moved to API. An example can be found:
