I have deployed cluster autoscaler, and it's running, but the logs are showing something failing, do we have any idea why it's happening and how to fix it.

Cluster, networking everything is in same compartment.
I referred this documentation: https://docs.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengusingclusterautoscaler_topic-Working_with_the_Cluster_Autoscaler.htm
