Briefly, this error occurs when you try to create an Elasticsearch policy that already exists. Elasticsearch doesn’t allow duplicate policies, hence the error. To resolve this, you can either delete the existing policy before creating a new one with the same name, or you can update the existing policy if you want to make changes. Alternatively, you can create a new policy with a different name if the existing policy is still needed.
