The page https://docs.openshift.com/container-platform/4.13/nodes/cma/nodes-cma-autoscaling-custom-install.html contains an example for a "KedaController" object.

The example does not work, as the field "omitStages" expects an array, not a string. So the KedaController example needs to be fixed to have the right syntax.

Custom Metrics Autoscaler documentation (4.13, 4.12), maybe other versions are affected as well

Always

1. Visit https://docs.openshift.com/container-platform/4.13/nodes/cma/nodes-cma-autoscaling-custom-install.html
2. Follow the steps outlined to install the custom metrics autoscaler

Creating the "KedaController" object in step 8 fails due to field being a string and not an array

Examples work without any errors
