mistake in example usage for yandex_mdb_elasticsearch_cluster

[cornzange]

If i run an example usage for yandex_mdb_elasticsearch_cluster, then i have an error

Error: Unsupported block type on elasticsearch.tf line 28, in resource "yandex_mdb_elasticsearch_cluster" "yc-elasticsearch-beta": maintenance_window { Blocks of type "maintenance_window" are not expected here. Error: Terraform exited with code 1. Error: Process completed with exit code 1.

if i remove block "maintenance_window", all works fine
