Line 1 in 06d87a6

terraform import elasticstack_elasticsearch_tranform.my_new_transform <cluster_uuid>/<transform_name>

Typo, this resource does not exist:
terraform import elasticstack_elasticsearch_tranform.my_new_transform <cluster_uuid>/<transform_name>

Correct:
terraform import elasticstack_elasticsearch_transform.my_new_transform <cluster_uuid>/<transform_name>
