oh ok! A quick question @Rahul K ! Are you still using /databricks/init as it relates to the legacy global path? Have you tried saving the cluster-scoped script to a different location such as /databricks/scripts ?
@Rahul K - Databricks recommends you avoid storing init scripts under /databricks/init (which is now a legacy) to avoid unexpected behaviour. Try using the new Global Init Scripts using either the UI or API or Terraform and see if the issue persists...
